This video is solely focuses on repression/censorship of sexual desires. It barely touches on the broader issues of self censorship as discussed in the article posted by Andy regarding that professor who was on some conservative black list, and the PC police (and that other group for which we now have an alternative name for on this board** ) as mentioned by myself on occasion.
**which by the way, is an example of self censorship...
Back on topic:
Whether it is socially acceptable or not, males tend to be very sexual beings. It is in their nature (unless it's been socially repressed) to seek out multiple partners.
In terms of being aggressive, well I think that leads to increased sexual excitement which allows men to ejaculate sooner rather than later. Why is this relevant? Because quick successful copulation was vital to our primate ancestors..in order to pass on their genes, they had to do it quickly before a larger/stronger competitor stopped an attempted copulation, and passed on his own genes.
That is not to stay that causing a female partner harm is OK. However, any expression of sexual fantasy that is not within "acceptable" limits will be ostracized as perverted. But what is acceptable changes over time. "Doggy style" was considered perverted ("animalistic") in the past, which is why the missionary position was so popular for so long. And perhaps I've been out of the loop for a long time, but it seems that up until the past 5 or 10 years, anal sex between a straight couple was viewed as unacceptable. (I personally don't remember anyone mentioning it before then). Regardless, my point is that standards change. And men want to be able to function within society without having to carry extra baggage, so they repress these feelings.
I personally believe men should be free to express themselves sexually (or in other ways), with the only litmus test being violent/harmful behavior, which should never be tolerated.
