Yeah someone posted something a few weeks ago saying he saw a girl here rinse out his used rubber, implying he thinks they're reusing them here. I've been here about 7 times (almost time to punch in a free HF visit on my frequent flier card) and I've never seen evidence of that. But clearly that warrants some diligence and paying attention when they're bringing it in the room. I notice that they usually bring it in a paper towel along with the lube. So I just look to see if it's fresh or, god forbid, already stretched out or something. Probably a good idea to notice things like that.
Someone suggested bringing your own condoms but I'm married. It's hard to hide shit like that from the Mrs. This hobby is hard enough to keep secret I don't want extra evidence of hanky panky laying around if I can help it.
