As with most guys, I started with my hand. After that, I think it was sticking my cock under the mattress and above the box spring to hump away. Because my wife is rarely interested in sex, I still use some of the regular frottage methods. When my wife is interested but doesn't want me to cum in her vag, I sometimes thrust my erection against the sole of her foot to finish. Women's bare feet still have a hold on me. Foot kissing and licking and toe socking keep me erect. I like to lick my load off her foot too. That's why I'm "legsfeettoes."
