I thought about that recently too.
It's been almost a year since I had sex for the last time and I remember the next day waking up my first thought was: "damn, gotta wash bed sheet and blanket again."
And coming to think of it, I don't miss kissing either. I came to the conclusion that all this sex stuff is overhyped by media and dump people, I will just wait until I meet a person that I truly care about which I actually want to get close to.
Until then, why would I waste time on touching other people again? It's not even fun.
