i've only ever cum in a certain way: completely alone, laying face-down in my bed, watching some kind of porn, and using my clit. i've tried fingering, laying on my back, etc. it feels good but i cant ever finish. my boyfriend left me over it. any time we'd have sex, id have to cry from the pain of certain positions or lay there with only fake reactions. we've been together for nearly a year, i lost my virginity to him a few months in. He got tired of the sex. I dont want a new boyfriend because i dont want to be a prostitute. i dont know what to do.
