IIN for a mother to want to

Being intrigued by possibilities and even sexually aroused by those guys is fine and something not really under your complete control, but what you do about that is entirely a matter of choice.

I suspect if you were to try to imagine how you would have reacted if your mother had gone cougar on you when you were in your early twenties and dating, you'd come to the conclusion that it probably wouldn't have done much positive for your relationship with her.

It's perfectly normal for you to be very interested in sex, particularly since you're in the age range when women are typically most interested in it and you ain't getting much. If you're reasonably attractive, not a total asshole and you'd like to find out what it's like with a much younger guy now you have much more experience than you did at that age, then you're not asking for the moon. Some men in their twenties are seriously into the whole concept of being with an older woman who knows what she wants and knows how to make a guy very happy in the sack (and is maybe just a little bit grateful for their attention). But hitting on your daughters' boyfriends just because they're convenient and tickle your fancy would not be cool.
