"I saw the comment from anonymous about prostate fun and decided I had to write. I've been reading this blog for a long time and everytime there was a post about ass play I thought what a load of gay bullshit crap. Right up until got my first prostate exam. Talk about an instant hardon and bent over that table thought I would gonna shoot right there. I kept my back to him to pull my pants over my dick so he wouldn't know. It took some doing but finally my wife agreed to use a strap on and I blew biggest load of my life. Now whenever I want scream out loud toes cureled orgasm I'll lay down and toss my legs in the air and she straps up and plunges in. I swear to you my straight bros you want to cum and cum hard like never before you gotta try it."
I hate to break it to you, but I'm pretty sure your doctor knew about that raging boner. From the view he had, and the position of his finger(s), an erection is pretty difficult to miss.
The root portion of the shaft runs along the Perineum (the Taint) and the girth matches the part of your cock you can see,
There's a reason for that full-on boner, or at least a semi, during your prostate exam. Pressure on the gland helps with blood retention in the cock. You can test that theory by using external prostate pressure at the very root end --- right above the anus.
It's taking straight guys years to catch on and understand what many gay men have known and experienced for ... well, forever. The male G-Spot is the prostate. As the idea spreads, the issue becomes --- as you've found out --- convincing their wives and girlfriends of that. As Dan Savage keeps saying, partner satisfaction in the bedroom is all about GGG (Good, Giving, and Game).
Not convinced yet, straight dudes? There are options to try it without anyone else knowing. The Aneros Prostate Massager, or even the Butt Plug.
The other thing that should make it perfectly clear that the prostate is a pleasure palace? Try externally massaging your prostate next time you jack off.
