During college, I offered to give guys a ride home if they were walking on the main drag after the bars closed. Despite being incredibly nervous because this was a "family values" kind of state, once they were in my car I figured "They'll probably say no, but the worst they'll do is ask to get out." I assumed they wouldn't want to attack the person driving them, but you never know. In total, I asked 7 different guys if they'd like head... and low and behold, all but one of them said YUP! The guy who said no was surprisingly nice about it too, not even offended. The other 6... were a lot of fun.
Why is it I stopped doing this? Hmmm.
