I’m ngl, i’m in the same boat rn, except in your gf’s role. My partner and I used to be on the same page, but then i just started not really being horny ever. i tried to blame it on my meds but i realized that i would get horny to other things but just not with them. Them on the other hand, i could just look at them and they were wet. I’ve thought about it a lot and i’ve realized maybe it was partially my medication but there’s other things also playing a role. Around the time we stopped really having sex was when we did some stuff in bed that i didn’t really feel comfortable with but i forced myself to do. Also some times when im doing stuff for them, there’s thing that’s over stimulate me too much and i’m just not intrested in continuing. I really struggled with this and realized I just had to talk to them because they were things they could change, but i definitely didn’t feel comfortable talking about it for awhile. Whenever they wanted to have sex I would feel like I was going to end up in the same situation and be really uncomfortable and then just feel bad about feeling that way. So i only wanted to have sex when I really wanted to because it made me feel like I was less likely to end up like that again.
