Desires??

Okay so here's the thing. I had sex for the first time a couple of weeks ago (I'm 21) and since then I've got no sex drive at all, today I tried to have sex with my boyfriend and it kind of felt good but there was no amazing feeling like when we just rubbed our parts together (I could actually orgasm because of it) and this time... It was just meh~ he kind of got mad because I told him I wasn't really feeling good
