I'm 31, well going to be in a week. I have a 19 year old who wants to get with me, a 21 year old, a 50 year old and a 38 year old. The older ones I can understand, the younger ones not so much. The question is why would a 19 and 20 year old want me?

It's called experience and wanting to have a fling with an older women which is something all young men dream about. They have absolutely nothing to offer you except you,  but age is what it is and you would be viewed as Mom with their friends. 

So unless you want to be a coyote with a younger man, best find someone your own age and let these youngsters find their macho egos elsewhere. Good luck
