I guess what I'm saying is I just wanna make sure that my dick doesn't fall off...
I will share one thing about smokers and oral sex. I man posted last year about a icy/hot feeling he had on his penis after he had oral sex. He was really scared and went to the doctor and posted here well. Comes to find out the girl was a heavy smoker and smoked the strongest menthol cigarettes available. All came to the conclusion that the irritant was from the menthol.
Its an oil base so he washed it a few times and later told us it went away. Go figure!
Smoking has nothing to do with STD's. Risk is the same from a smoker or no smoker.
