Really Want It

Mwm senior with lovely wife who's pretty much shut down sexually. Like many on here I have been thinking about m2m for just recreational sex. Have not hooked up with anyone yet but feel it's becoming almost obsessive and jacking off to these nasty thoughts.
Imagine getting together with an older bear sort of fellow and really licking and sucking his balls getting him moaning and dripping sweet dick juice and taking that cock in my mouth until he starts throbbing and pumps me mouth full. I always loved eating pussy and female ass so I imagine rimming a hot hairy musky man ass too.
Alternately I sometimes think it would be hot to do all the above but with a young sissy type and let him finish me in his mouth while I have some of his cum still in my mouth.
Like I say it's so far just in my head but what do you people think?
Advice?
