I'm 50 and have made love with 8 women in the 32 years since my first (who was also my ex). One of the eight was my ex. One, of course, is my wife now of 11 years. 4 were in the single years between the two wives and were all very sexy, engaging ladies with whom things just didn't work out, for one reason or another. The remaining 2 I regret for they were spur of the moment and meant nothing.
I often think back on them all and in a very male kind of way try to arrange them into who made love the best, who was the best in oral sex, who had the best body, the prettiest face, etc. I always decide I have ended up with the best overall, even though she is 10 years older than I.
All in all, since the first time at 18, it's been a good ride (pun intended).
