Im a 40 year old married woman, why am i so attracted to young men?

Theres something about them that drives me crazy, Im always checking them out, exchanging seductive glances. One time I was with my husband and i blew a kiss to one. (good thing he didnt see!) I went to the bar with a couple of my girlfriends and there was this 18 year old guy SO hot. Im not gunna tell you what me and him wound up doing, but why am i so attracted to young men? HECK! sometimes I go out looking for them!
