Ok, I meant not genrated from the parties participating. The actual penetration part, if all other noise was discluded. I have no idea why this came into my mind, but it did, and it won’t go away.
uh… it can make noise, if your exertions are particularly vigorous and legs, stomachs, whatever are slapping together. This is more of an issue if the man is standing–>freer movement.
My guess is that oral sex developed because lips & tongue are some of the most sensitive areas of the body. It feels good to have them stimulated (smoking; chewing pens; sucking spoons; kissing).
hey, take it easy on ol’ Speak. Yeah, the activities associated with sex make noise, even if its participants don’t. There’s skin on skin, as well as the sounds made by other parts of the people in motion. Any person moving with any other has to interact with something in order to move, some supportive surface or something. These interactions, whether with a creaky bed or a pup tent, usually make noise. So, yeah.
As for when oral sex started, who knows? I’m sure people have been engaging in oral since they discovered that sex is fun. It’s like an anthropology question: when did people start engaging in sexual activiy for recreation? Did homo erectus start this? Sorry, couldn’t resist.
While the effect of the moonrise on the ambient noise is probably negligible. The sun does in fact heat the air, which can create a noticeable ‘noise’. Not to mention the fact that a number of animals use it as a trigger to become more active, and hence create a considerable noise (usually right outside my window). While both these ‘noises’ are only created in a rather indirect manner and are not totally synchronicity with the actual sunrise I always associate them with it.
