Perseus -
I'm not experienced at giving reviews, so bear with me, but I'm going to take a stab at it.
I like the pics - no penis shots to be had, and that tells me that you are more than a Dick
That's great!!!! Most women looking for a man or a couple that are looking for that 3rd dont want to have a penis wagging in front of their face 1st thing.
One part that has me concerned is this "or maybe a married ladywho has been playing alone." To me, it sounds like you are condoning cheating and true lifestylers look upon cheating as a no-no.
I like the part about it being an honor being invited into a couples bed though - it seems like you have a handle on what it means for a single man to be invited into a couple's play.
Maybe add something in the fantasy section or share some of your experiences, but with out details.....this gives folks looking at your ad a feel for your experience...
I'd take out the part about being fairly well-endowed. Remember you want a single woman or couple to be interested in more that your penis and its size.
All in all, a great profile!!!!! Maybe one of the single males can give you some tips, but I do like it except for the few points that I already made.
Hope this was helpful!!!
