Common on here, rare in life...
It's not rare, it happens all the time. There are certain avenues for it, such as (certain) massage therapists. It's easier for straight guys to receive then to give. Since girls don't have a dick to put in their butt they'll search for it other places too. Liking to take it up the butt or any sexual experimentation doesn't make you gay. It's too bad we have a double standard that women can experiment and still be straight but men can't. That's something I get personally offended by even though I am gay. It's frustrating and awkward for the straight world.
