I don’t think my boyfriend and I have enough sex and I’m pretty sure there’s something wrong with me

I’m 20 and lost my virginity to my current 28 year old boyfriend 6 months ago when I was 19. This is also my first relationship ever.

I went on my first date with him Thursday. We had a really great time so we decided to go on another date the next day. The weekend passes and he says he wants to make me dinner at his house in Monday. That’s the night I let him take my virginity and we decided to officially date.

Since then I feel like our sex life is pretty dry. At this point we only have sex every week and a half for one round that lasts like 20 minutes and that’s it until the next time. Personally I would rather us have sex at least 3 times a week but I’m not sure that’s possible.

Im pretty at fault too because it’s really hard for me to initiate and obviously I need to initiate more, but the thought of my boyfriend rejecting me, even if it’s a small excuse like he’s just tired, makes me want to burst into tears (one of my red flags something is wrong with me). I don’t want to tell him this though because I’m afraid he’ll feel obligated to not reject me and I don’t want him to do things he doesn’t want to.

I’ve talked about our lack of sex to him twice. Once in the beginning of the relationship where he said he usually gets the opposite talks, that his past girlfriends and boyfriends wanted less sex than him, but he promised he’d try and do better (after that our sex life dropped off more to be honest). The second time he said a lot of his relationships were sex based and he just wants a quality relationship.

Now I feel stuck, because after 2 or 3 days of not having sex I get antsy, sad, and (another red flag) angry. I hide these emotions cause I don’t want my boyfriend to think I’m dysfunctional I am and sometimes I feel like there has to be something wrong with me for wanting so much sex.

When we do have sex all those feelings go away. I feel validated in our relationship when we have sex, but I can’t rely on that because it’s not very frequent.

I love him a lot and I would never break up with him for something so petty but some nights I feel like I’m losing my mind.

I don’t know I need help please
