I concur, and anal play is fun. Now you might not find a lot of guys to either admit to it or even do it, since some do not keep an open enough mind to try. Therefore they don't actually know whether or not it feels nice.
Indeed it of course feels nice, but some are just not up for giving it a try.
An example of this could be in a different context. I remember a friend explaining how he refused to make out with his gf after he came in her mouth. He said "That shit is just nasty and I would never taste my own 'jizz', would you?"
My response was "Dude, hell no, but I still would make out with her so I cant agree with you completely"
Even though I didn't admit to it, I have indeed tasted my own cum. Never used to like it until recently when a few girls dared me to lift up when I am about to do so and have it go into my mouth. Wasn't really "good" still although the thought dwelled on my brain for days. Eventually I tried to do it atleast once a week.
Hell now I actually have learned to like it, and find it to be a turn on when I do so. (Funny how your taste changes. I used to think it was salty as hell and for some reason it taste sweet after about a month or so of experimenting)
Anyway, that could be another story all together.
The point is people don't always tell the truth since sometimes somethings are best kept to yourself, while other times it is fine to express yourself
By the way, in case you are wondering, I am 100% straight haha. I cringe at the fact of being with another dude!
Although I do wish my mindset was different, meaning bi. Why you might ask --> more options & choices obviously. Oh well, I just have to be lame and stick with being straight =]
Hopefully this helps.
