why does my girlfriend not want to have sex with me?

Most women get turned on by romance, not so much the "sex" part of it. Maybe you could try a romantic date, flowers, etc. where she is the center of your attention. Or if she's stressed out, do something nice while she studies (like get the oil changed in her car or get it washed, or do her grocery shopping). No matter what, you should actually have a conversation about it with her. I'm not trying to sound rude, but if you are mature enough to be having sex, you should be mature enough to be able to talk about it.

By the way, I'm assuming you are not high school students. Because if that's the case, maybe she doesn't want to have sex because she's just not ready but is afraid to talk to you about it.

I’m not sure exactly how long you’ve been together but you are pretty sure that you want to marry her, which s great. =)

You asked if it might be a problem with you, have the two of you ever been intimate?

Or have you spoken to her about the it, in a way that she doesn’t feel that she is being berated but supported.

Is there a possibility that it may be linked to past experiences?

Explore new options, couples therapy if you both feel its something that’s getting in the way, introducing new things to the bedroom; from foreplay to tetra.

All the best!

Because she doesn't want to. Is that really so hard for you to accept? Maybe she's a virgin and she doesn't want to have sex yet. Maybe she's been used by guys before and doesn't want to go that far with you yet. Maybe she's not keen on sex at the moment because she's got other things going on in her life.

Or maybe she's just a bit worried about the fact that your thinking marriage, and maybe she's not. Who knows?

Tell you who might actually - she does. Why not ask her?

No, it's more like something is wrong with you! Not only do I think you're probably pressuring her too much, but have you considered the fact that you don't have to have sex? Sex is a privileged, not a right.

Have you ever asked her? Maybe she wants to wait until marriage. Maybe her pills are affecting her libido

Maybe you have a tiny dick and she doesn't get turned on by it

ASK HER! Because of course a whole bunch of randoms on the other side of a computer screen are going to be able to tell you.

Maybe she's she waiting until marriage. I wouldn't have guessed that either looking at these women you see most of the time.

Maybe she's old fashioned and doesn't believe in sex until after marriage?

dont listen to other answers saying she's sleeping with other blokes.

its simple mate: she isnt ready. dont force her into it. show her you can wait and who knows the time might come sooner than expected aye :) good luck bro

it could be the meds. a lot of medications cause low sex drive.

she is probably not ready. if you love her just accept it, don't rush her into it.

or maybe her libido is low.
