So me & my bf have been together for a year & a half & lately the Sex just isn't as good. Idk what it is. Lately there's been problems going on between us we figure it out but the last few arguments have made me more insecure about myself but at the same time makes me think bad about him because he also makes me feel like he's cheating I get to the point where I start feeling like I'm not enough for him & I end talking down on myself. I then get in my happy moods & think well maybe I'm over exaggerating and it's just me. But as I said the Sex isn't as good anymore I don't desire him the same as I once did & lately I've been feeling like he doesn't really desire me as much anymore either. About 3 weeks ago he didn't even ejaculate & the mood over all just doesn't feel right anymore. Idk if it's me getting over his shit & him being over us or if he's getting some loving from someone else. Idk what to do because usually I'm pretty open with him with how I feel but this just is something I can't stop thinking about & I wouldn't know how to approach it. I mean I get happy to see him but just not the same as before because there's always shit running through my head about him. Or maybe it's just trust issues?
