i was wondering if bbbj is safe. and should you do it?

There are those who say it is, and those who don't.  If you do it depends on your comfort level and if the lady offers it or not.

if it was a new girlfriend or a girl you met at a bar?  If yes, then don't do it, if not then go ahead.

Clint Eastwood says, " Do I Feel Lucky".

Can you get an STD from a BBBJ?  Yes.  Are the chances high or low?  That depends...
