So I see answered an ad for msv the other day. I masturbate a couple of times a day. I like doing it and I do it well. So I decide it's time to get paid for it. I start doing it and I get into it but I can't finish the job! So we ended it, I got paid for what I did and then I said goodbye and left. What gives? What happened and what can I do to prevent it if I ever try to do it again?
