I wanna have SEX

My bf doesn’t want to make sexual advances towards me because he doesn’t want to seem like a “HoRn DoG.” But in actuality I’m just assuming he doesn’t want to because he’s not attracted to me. Whenever I try talking nasty, he DOESNT get the hint, or he tells me he doesn’t know to say. Keep in mind that I’m his first girlfriend! Neither of us don’t have our own place yet (fresh out of highschool, he’s going to basic soon and I’m going college in August) so we usually have sex at the beach, in the car, or some other places and it S U C K S. He’s never made me cum, and he has such a hard time cumming!! In our five months of dating, he’s only came TWICE !!!! From sex. Oh gosh the fact that it feels like he avoids me makes me feel so unattractive. I think I’m going to beak up with him soon because I just want to get pounded like a WHORE !!!! I’m not even kidding guys 😭😭 I’m sorry I just needed to vent !
