Maybe she doesn't trust in your faithfulness or she is being very careful not to get preggo.

She doesn't feel like breeding?

She obviously has an std .

Have you been 100% faithful? Chances are she just really doesnt want to get pregnant? Or perhaps she has something like thrush? It can be caused by non sexual things but can be passed on through sex and its MUCH harder for guys to get rid of than it is for women. So if thats the case she has your best interest at heart!

She may be having an affair. Or she may think you are.

She is cheating, final answer...

Based on your comments under the other answers, I hate to say it, but she may very well be cheating on you, or has caught an STD that she doesn't want you to know about.

It's probably one of the following: 1) She suddenly is suspicious of you. 2) She's cheating and in her own bizarre way is trying to protect you in case she has caught something. 3) She does not like the feel of semen inside of her (this is least likely to me because she probably would have mentioned it a long time ago). Either way, you and her need to have a long honest talk. Maybe i am biased, but if a man takes the responsible action of getting a vasectomy, he should expect to be able to have unprotected sex with his wife.

She insists you wear a condom. You had a Vasectomy. She has trimmed the forest. Dude shes cheating on you or at least had a fling and is making you wear a condom until she finds out if she contracted an STD. Find out who she slept with and pack all her belongings up and deliver them to him and wish them luck. Cheaters deserve cheaters not decent people in there lives.

1. She doesn't trust you and has no idea where it's been. 2. She wants to make doubly sure she doesn't get pregnant. 3. She's been fooling around and wants to make sure you don't catch anything she may have picked up.

Yeah about that. I forgot to tell her that I had the clap when we had sex last week. My bad!

Well, SHE "Might" THINK that YOU are cheating on HER and to make sure that YOU don't give HER an STD , SHE has YOU wear a condom .....OR ..... Maybe SHE cheated on YOU and now is afraid that SHE has an STD that SHE doesn't want YOu to catch it ...

She's been monitoring your activity over at AB4Adults! Smart woman! :-)

If SHE suggested it, and she "trimmed" when she never has before, then it sounds like she has been stepping out. Does she wear more jewelry and perfume than before? Does she take more showers? Is she "not in the mood" quite often, when she used to be quite a bit? Does she go out more often (like shopping, or hanging out with the girls, or getting a drink with the gals, after work)? Look for the signs ... if you see none of the above, you may be fine, but, if she has changed her routine quite a bit, I think you may have to confront her. I'm sorry, and I hope I'm wrong!

Ask her.

She doesn't want to get knocked up.

Either she thinks you have something, or she knows she does.

Maybe she has come off the pill as there is a lot of controversy about the side effects of it these days.

Considering your other questions, she probably is tired of cleaning up after you masturbate.

she cheated on you and got an std but doesnt want you to know

sounds like she suspects you of cheating

Unfortunetly, my guess would be that either she thinks that you are being unfaithful to her or she possibly could be being unfaithful to you. Have you asked her?

Could it be that she found some kind of condom that is supposed to excite a woman? Otherwise it may be bad!

It's those days where she can't take a chance.

she probably thinks you are wandering in your playtime with other playmates.

Maybe she doesn't want anymore kids or she's not ready to have kids at all.

Aren't you a woman? Pick a gender, it's impossible to be both.

Cheating.

Did you ever think she's testing you to see how you will listen to what she says? Of course she wants you to wear it for sex but you can take it off...after all you've worn it for 3 days!

Give me her phone number, I'll ask her. Or, you could.

Most likely because she doesnt want to get pregnant and usually birth control falls on the woman.. Now if she is like me, remembering to take the pill at the same time every day almost never happened... got pregnant... Then I tried the depo shot, and well, felt really crappy for a few weeks after every shot, and eventually got pregnant again... I have a much better, more reliable form of birth control now, but if it wasnt for that, you bet your ass my husband would be wearing a condom, or else he wouldnt get any. Plain and simple. No offense or anything.. Take turns sharing the preventive measures!! :)

i don't mean to get personal but do you have anal sex? cause if you do it back and forth bacteria can cause some bad infections so she might not want to get any. but you should ask her. Also she can get bateria from other things to and the male partner can get it but have no symptoms and she would treat the male would keep bringing it back. well hope everything goes great!

Why not 'ASK' her communication is the best approach

One of two reasons, so ask her and see which it is.

You aren't legally required to wear one so if you don't want to tell her NO. Then hint that you are in the mood for some intimate contact and see how she reacts then.

She doesn't want more kids?

Maybe she's not cheating. Maybe she is unsure of the future of the marriage, and doesn't want to get pregnant.

she probably doesnt want to get pregnant. My gf doesnt like the pill because it messes with her head so she would rather just use condoms. Either I wear one or she wears a female condom. Not a huge deal.

How do you use a condom? * Open the condom package at one corner being careful not to tear the condom with your fingernails, your teeth, or through being too rough. Make sure the package and condom appear to be in good condition, and check that if there is an expiry date that the date has not passed. * Place the rolled condom over the tip of the hard penis, and if the condom does not have a reservoir top, pinch the tip of the condom enough to leave a half inch space for semen to collect. If the man is not circumcised, then pull back the foreskin before rolling on the condom. * Pinch the air out of the condom tip with one hand and unroll the condom over the penis with the other hand. Roll the condom all the way down to the base of the penis, and smooth out any air bubbles. (Air bubbles can cause a condom to break.) * If you want to use some extra lubrication, put it on the outside of the condom. But always use a water-based lubricant (such as KY Jelly or Liquid Silk) with latex condoms, as an oil-based lubricant will cause the latex to break.

how the hell do we know? prehaps she dont want to get pregnant thats the biggest reason people wear condoms. she may think youve got an sti or she might think she has either way the only person in the world who can answer this accuratly is your wife so ask her instead answerbag is not a psycic site sorry

It's either because she thinks your cheating and might give her HIV. Or she's cheating and don't know if she's contracted HIV.

for safe sex most likely

Maybe she's in the mood

Since the #-1 reason to wear a condom is to prevent the spread of STDs .... 1)Maybe She THINKS you may have been cheating and is afraid that YOU will give her an STD .... O R ... 2) Maybe SHE has been cheating and is afraid that SHE might give YOU an STD .....

I have no idea. She has no problems when I don't wear one

what a question..

Have you been eating a lot of asparagus lately? There's one hell of a good reason if you ask me.

I'll bet your wife is the one to ask.

I agree with the others. It sounds like she may be cheating on you. It sounds bad. Find out.

She is a thoughtful wife who doesn't want you to catch something.

Surely if you are married and having sex together you could ask her? Or is that too personal?

either she is afraid to get pregnant or she thinks either she may give you a disease or you may give her a disease~maybe she don't want your juices in her? ASK HER?
