Being 42 I can see maybe a 27 year old. Anything under that seems to be very immature and they have even shorter attention spans and will get bored.Aside from a sugar daddy/sugar baby relationship, I do not see how this could be possible or probable.
Here in Florida I see like 52 and older men with women who're like 30 years old. Not often as it's a very old area I live in but I do see it from time to time. It's easy to see why. Look at Anna Nicole Smith and Katharine McPhee for example. Do you think them two would go for a senior if they were living off social security and having to work part time at the local market to survive?
The grocery store I work part time at we have a number of cute girls, I mean HB7.5 ages 16 to 23. The 18 year old ones and up are NOT dating 40 year old guys. Their boyfriends are around their age ranges.
