I go commando sometimes as I find it really turns me on, but if I do it too often I get used to it so it isn't as exciting.
I also have to be careful what trousers I wear as it can get the pre-cum flowing.
Commando? No not likely men need support, balls and cock slipping down the wrong trouser leg can be extremely painful. My wife often doesn’t wear panties although increasingly she likes to wear what’s no more than some threads with cultured pearls attached which give her pleasure as she walks and even more pleasure when my mates know what she’s doing. She’s Anglo Greek and creamy white pearls show up very nicely on her tanned body, she knows I tell my friends and tells me off then thanks me.
