I'm the same, and judging by the replies you've got here Chance you seem to be part of the majority, not the minority!
For me, it's partly a confidence thing and partly because most of the cocky clients I've seen have tended to be the younger ones.
I also get quite a few texts and emails from guys enquiring about a booking that include a phrase along the lines of "I'm attractive, like to give pleasure and I'm 20 something so I'm sure you'll enjoy yourself" as though they expect me to be flattered by a young stud wanting to book me. I've even had guys asking for discounts because they're "fit, young, and you'll enjoy yourself babe"...
I do have a couple of young regulars who are polite and respectful and I get on with them great. However the majority are older guys, and I wouldn't swap them for younger clients any day of the week!
