Right. Oral sex is commonly observed in most primate species, both hetero and homo btw, so (at least if you believe in evolution and therefore think we are related to other primates) it seems likely that our ancestors had oral sex. Certainly by the time they became able to draw, sex in general (including oral sex) was a regular part of their subject matter, but that is far, far more recent.Probably, I mean if monkeys have enough intellect to do it, I'm sure our ancestors do.
I knew you were getting up in years but....They did not deep throat, however.
When no one washed the funk would just have been perceived as normal. Oral sex is probably as old as sex itself.
I'm betting no. Sex wasn't really for pleasure for women back then...
