Should be ok, as long as she didn’t leave you gagging

Completely understand about the bad knees. Too much playing catcher when I was young and letting the Army throw me out of planes really took its toll. I primarily use an elliptical now for longer cardio, and I walk on a treadmill doing a modified 30-3-12 workout prior to lifting weights. Neither of those is good while naked, but once I hit the weights or other exercises, I love being naked. Thinking about trying it while wearing a plug to add to the spice.
Maybe I’m late to the game, but have any of y’all ever worked out in the buff? I have a small home gym, and after my time on the treadmill today, I had the urge to shed my clothes and hit the weights naked. It was both exhilarating and stimulating. Anyone else try this? Or am I just weird?
It depends. There has to be some attraction. I have been in MFM’s where the other guy didn’t do anything for me, and it was all about just focusing on the F. But other times, I’ve have no problem to engage the other M, to include sucking them off, especially if I’m cleaning her pussy or ass juice off of his cock.
