It'd probably be a good idea.
My last three near misses were:
A guy who claimed he was married when I turned him down. (Seriously, if a dude asks another dude for his phone number within 60 seconds, there's no other possibility right?
Kniper?)
A fattie with a huge herpes sore who hit on both my married friends but not me.
An even fatter fattie with no obvious diseases.
Oh, and before that, a murse in an oncology ward tried to pick me up while I was visiting a dying friend. Classy?
However,
I have no skills.
I don't dance.
My erections can't rip holes in my boxers.
Is that a problem?
