Very few people smoke now a days, specially among younger gay men.
I think clients who smoke don't mind hiring an escort who doesn't smoke, and escorts who don't smoke always have mouthwash available for their clients who like to smoke.
No, I don't hate them. I'm glad they have the stomach to have sex with gay men for the money.
Some guys on here only hire straight men, to each his own. Personally I'm into the BFE and I'm more likely to get that from other gay men, besides in the Navy I had so many real straight men...
