I haven't been having sex at all for a few months now and I have no idea why. I mean sex is fun and all but I guess I'm too lazy to actually try and pursue anyone for sex (even when I had some girl who I knew wanted me to fuck her brains out and she has been in my bed TWICE, but I didn't do anything, I didn't make a move, I just didn't care). I am not gay or attracted to guys in any way so I have ruled that out. I am however extremely scared of STD's. All STD's freak me out herpes, AIDs, Genetal warts, even crabs (not a disease I know). I see commercials promoting medicines that keep herpes outbrakes from happening on popular channels; so I am deducing from that that there must be some huge portion of the human population that have these diseases. I'm clean and I want to keep it that way. I am probably not wanting sex because I am subconsiously knowing that I dont need it or it's not worth it because of those diseases. I might be wrong though, can anyone help me figure this out I'm really not knowing what is going on with anything so please, if you have any sort of idea of what my problem is please post it.
