if he is just a boytoy, why does it matter? My feelings aren't the ones that are going to get hurt. The worst that will happen is this will become something physical, and we'll fuck, and he'll cheat on his girlfriend. He'll get hurt, she'll get hurt, I'll lose a friend/fuck buddy. Seeing as I'm not close to the dude it won't be a huge loss, and in the mean time I will build my confidence back up because I will be having good sex that I prompted with someone I trust who will be telling me that it is good, plus letting me switch and experiment.
Basically, it sucks that people's feelings have to get hurt for me to feel better about myself, but I'm a bitch and beyond caring. Like I said, I never claimed to be a good person.
