yes. it's creepy...i don't want a dog or cat watching while i'm pouding the daylights out of some chick :)..

i keep my cat out of the bedroom at night even if i don't have a girl over...i don't like cat fur all over my sheets...

Whatever turns you on, man? If the pet doesn't distract either of you or otherwise get in the way then you shouldn't worry about it. ..

Generally I'd be creeped out by it, but one afternoon after sex I noticed my two rats staring at us in what looked like wide-eyed horror, their tiny minds screaming "THAT IS HOW BABIES ARE MADE?!"..

Hahaha! I love this question, it's soo funny. It's not like it's BAD to have a pet on the bed while having sex, but it's definitely awkward! Once my cat jumped up on the bed and started PLAYING with the condom He had just put next to him.... I put her out immediately. lol! Cats are weird and I think animals know what's going on. It's just weird. Make sure to leave them out of the room! =]..
