so early this morning me and this guy i have been seeing for a month got a frisky. i just wanted to jack off together but we ended up humping,non-penitrative,but really rough naked humping. My dick was right at his back-door and his was near mine. we both precum alot,but we stopped only because he was grinding..humping wat ever u want to call it on my dick so fast it was starting to get a lil painfully sensitive from being dry i guess. anywho so when we finished i rinsed my dick off with soap (forgot my ass) and went to sleep. when i woke up it kinda stung to piss (but i figure thats from the soap and my large piss slit) and my ass is kinda bothersome (i guess thats the best way to put it). the guy i did this with donates plasma and did it this past sunday (so im hoping that shows he was honest when he said he didnt have anything). only thing that bothers me is the fact that sunday i had some rather rough penetrative sex (with condom) and my ass kinda hurt for a day or two after... what are the chance i'm still clean? =/
