Backstory: So I've been dating this girl for a while now (9 months). We've been friends since elementary school, had some sexual tension build up last summer and we both decided why the fuck not and hooked up. Everything's been pretty great so far, no complaints.

Well not exactly, the thing is I happen to be a guy, and like most of you, I also happen to enjoy sex. It's not just the physical sensation, but a good fuck reminds me that we're passionate about each other and that keeps my spirits up.

I get that in the beginning there was a lot of sexual tension and we were letting it all out, doing it maybe 2-3 times a day, and that isn't how real life works. The thing is, we rarely get to fuck during the week, maybe once or twice if we're lucky (note: we don't live together) and it seems like whenever we have a window of opportunity she just isn't into it.

Now here are a couple things I thought I'd mention:

  • Once we're actually doing the deed, she LOVES the sex. Lucky for me her ex-partners weren't great lovers and she goes nuts when I tease her/eat her out/give her full-body orgasms. When we're done she always says that sex makes her feel great afterwards, we should do it more often, etc. It's the next few days where she just never seems into it like I am, which makes my guy brain go "why she no like me :(" even though I know that's retarded.
  • She's VERY self-conscious about her weight and she told me it's affecting our sex life because she feels like I deserve better. She isn't "fat" btw, when we started going out she was 5'2'' and 120 lbs, now she's at 132 lbs. She has a little belly from eating shit food, but otherwise her body is fucking amazing and I remind her every 5 minutes or so (probably a bad habit, but wtv).

I really hate "asking" if now's a good time to fuck, I miss looking into each other's eyes and deciding without saying a word "hey, we've got about 30 mins... let's go for it". She rarely begs me to fuck her anymore, it's usually me hinting and sometimes flat out asking, which is kind of a turn off and makes me feel like a needy prick.

So I guess what I'm asking is, what's the right way to deal with her "not wanting to"? I don't want to seem like it's all I care about, and I don't want to push it on her when she isn't in the mood. It sucks because she loves the sex, it's just that she doesn't realize it until we're actually starting off.

So, seddit, how do I go about increasing my girlfriend's libido without screwing up what we already have?

edit: sorry if it seems like I'm posting in the wrong subreddit, but RelationshipAdvice is full of AFCs these days and I value seddit's opinion way more, no offense RA.
