Blowjobs

Have you ever been with a guy that says he doesn't really like blowjobs?
Or maybe you are one of those guys.
Let's see if any of these sound familiar:

1. "I really don't like blowjobs but I love going down on a woman."
2. "Maybe I just haven't been with someone who knew how to do it right."
3. "It just doesn't do anything for me but if you want to go ahead."
4. "I've never come from a blowjob."
5. "You can try but I'd really rather just fuck you."

All of the above have either been said to me or one of my friends. I find it quite intriguing. I can't figure out if men really have decided they don't like blowjobs or if these are just lines to make us work harder. Is it reverse psychology to make us try to please? Is it a contest? I dare you to make me come. I really just can't figure it out.
