For you straight dudes that watch porn do you see a level of homosexually encroaching it?
I'll give it a go. Yes. Yes I do.
It has been a rather gradual encroachment but has increased over perhaps the past 6-7 years. Even the larger pay per minute sites categorize things like transexuals and cuckholding in their "straight" section of videos by default. Then there are acts which many men may feel as emasculating, such as femdom, pegging, ass worship, milking, ect. that also appear in the straight category by default.
Then you have very popular directors like Jay Sin who make TS porn (TS Playground) right next to his staple of very popular, extreme gonzo porn (Gape Lovers, Anal Buffet, Anal Acrobats, Pretty Sloppy, ect). As a director, he has always leaned towards very extreme anal stuff and switching over to TS porn seems to be a very natural thing for him. His production company, Evil Angel, is made up of a vast majority of Euro directors that have no issues at all with TS porn, although few actually shoot it. You even have huge stars like Nacho Vidal that enjoys having sex with transsexuals but then goes straight back to hetro porn the next day. Even Rocco Siffredi dabbles in Shemale/TS porn. Other popular American porn stars fuck Shemales in various movies, from Belladonna to Bobbi Starr and many more. However, none of these people or directors has ever shot or participated in male on male porn. Shemales seem to be perfectly fine though. Oddly, many menfeel the same way. /shrug
The real page turner was years ago when old school American porn star Joey Silvera started shooting Shemale porn. He was the very first big name American to do it, and he had been in porn since the 80's. Dude was a "straight" porn star for 20 fucking years. The guy was an institution. I cannot think of another porn star/director here in the states that made the switch to TS porn like he did. Not only does he shoot Shemale stuff (She-Male Idol, Rogue Adventures, Ladyboy Adventures, ect), he also shoots Strap Attack (female fucking male) and a whole host of niche gonzo porn (squirting, cockhold, milf, interracial, ect.).
I'm old enough to have witnessed a plethora of formerly rare, deviant sexual acts working their way into mainstream adult movies. Back in the 80's, anal was rare. Now pretty much every single movie made has anal in it. Hell, ass to mouth is in almost every film now a days. Swallowing, cream pies, gaping buttholes...man all this stuff was in 1 in a million films in the mid to late 90's. Now it's casual fare. No big deal at all. It's everywhere. The entire adult film industry is constantly looking for the next major kink to bring forward. Shemales and other niche perversions are slowly getting pulled into the foreground.
It is all very interesting IMO. Shemales are not my thing, but I have a deep and varied love of many niche forms of both sex and porn. More variety is always a good thing IMO.
