I don't think the Post-T-Vac has the right "protection"......
I think the urban legend came about due to so many single ladies living in the Villages (one "bad apple"....). I have had a few folks toss the STD thing in my face and I respond "oh and you haven't heard of all the unique golf carts?"
STDs cover a large spectrum but nowadays everybody only thinks AIDS.....
IMHO just sayin....
