I wore my gfs only a few days ago, purely as I had run out of boxers though (honestly), but love it any way, have worn them for thrill in the past, used to love dressing in her stockings, suspenders and panties, stripper heels too, although since she watched a video that I filmed and forgot to delete on her laptop/webcam with me in her lingerie, she told me it didn't turn her on but was cool with it, so not as much these days, perhaps once every few months, when my bisexual side is on heat.
I once had xdressed in her lingerie for a 50 y/o guy off a swinger site, sucked his cock and let him spunk all over my cock while I masturbated then he watched me finish, that was fun, made me feel really slutty!
