That is what I was about to say. The only girls who I know who give blowjobs with a rubber on are prostitutes.
You guys can tease and say all the shit you like, but you know damned well that you don't have girls putting condoms on you for a blowjob.
And for all of those bitching and whining about herpes, etc., do you put a damned dental dam on everyone you kiss? NO? Well, I'll be. Don't you know you can get diseases, including herpes?
I just don't go down on any old person whom I just met. It has worked for me so far. I've never had any STD.
