I get what you're saying, however, you're not making yourself clear as it would appear that you might be having one night stands and the person appears to want to give you oral but you simply just don't get it? Lots of boys/men actually try to avoid it based on possibly poor hygiene and that golden oldie, it smells like fish, lol. All the above you mentioned is important but nevertheless a guy would seriously only go down on a girl he barely knows because he hopes that she'll then give him a BJ, plain and simple. If you're going to get your balls wet but there's a possibility it's not going to be earth moving, I might as well at least get a BJ, is what they're thinking. I know every guy thinks that he's Casanova despite most girls/women faking it, lol. I personally only go down on a girl/woman that I'm in a serious relationship with, however, should I choose to have a one night stand and she asks me to I would as even during a one night stand I believe we both should make sure each other is satisfied.
