Being in a similar demographic, I know a number of genuine mature ladies use AMM (adult matchmakers).
I had a threesome with one 68 yr old very hot greedy genuine lady with an active profile there just last night!


She tells me she gets more than 20 offers a day so they are in the drivers seat to pick & choose.
Also had a spitroast straight after with another 60yr old hottie-her first MMF (second M was a BBC only got the bj as he couldn't get it up after play with another girl) I met through the RHP website.
Thus ur first contact is important to grab their attention (usually not with a dick pic or I'll give U what U wish/long for, or I'll f**k U till U can't stop cumming, as these are boring to them & don't stand out)
