Well, I can easily masturbate once a day to IR porn, in my younger days until my early 40's 2-3 times a day... everyday. My wife does now and again, unless we are going to have sex, then she'll put her favourites ones on, play with herself , cum a couple of times, maybe get her 'Sammy' her big black dildo, cum maybe once or twice more, then once she's done, she MIGHT let me mount her and let me cum. Otherwise, she'll just watch me jerk off to it, cum, i'll clean up and she'll just roll over to sleep. We ALWAYS fuck to IR porn, its the only way she can get horny enough to let me fuck her.
