once i was watching at a shemale porn film with a friend of mine (former best friend actually) and get so hard that i wanted to take off pants and jerk off. i think he would have done the same ... but i didnt. maybe a shame or ... dont know. maybe would be nice to jerk off together but that "game" may go further and that's little frightening ho, now remember that at the childhood on a walk with some other friends we jerked together, but that's not a count - we were so young ( maybe 10-11 years old) that we didn't know exactly what we were doing
