Possible men (or not)

A, the 31 year old I met online, who actually seems kinda nice--at least at a virtual distance. Someone young would be a trip...but I fear I am too old.
D--the 50 something DOM whose marriage broke up because of his D/s interests (should I say obsessions?)--we are supposed to meet for dinner in 2 weeks.
DSF--the still cloaked (and married) DOM who is married with a child, smart as a whip and sounds great--but is attached (okay, he has done this before, but it bothers me)
There are some others from the dating and BDSM sites, but these men have caught my attention.
Now, do I actually meet them and move these options ahead?
I think yes.
