Strange thing I have with my fav. When I dwell on her, like when recalling a session, I get a boner.  Like when I was 15 in high school. Sometimes, it's just a chubby, but usually genuine glistening wood. This has never been a problem in my civilian adult life and only once before in the hobby. Mind you, this is a purely sexual response, I have no personal hang up with her beyond that moist snug V. And it's kinda fun, invigorating even. I haven't told her about this. My little secret.  

ONLY one woman makes you sport wood by just thinking about her?

.....and when I think back to her lips on me, all I can say is "clean up on aisle 3!!!!"

kind of... but my boner is limited to day dreaming about the next woman I'm going to see.... or maybe that last one I just saw... or maybe the SYT standing in line in front of me at Starbucks... or.. well, you get the idea...

The other gal who had that effect on me was a provider, but the boner only happened when we spoke by phone. I'd be walking through crowds, she'd say hello and boiiiiing. I have taken precautions by mixing in others. It's not a huge problem (given my size - haha) but it makes me smile when it happens. Usually I walk with a briefcase so I can shield the blush as needed.

Though it isn't as common as it once was, I often get an erection when thinking about a particularly intense love-making session.  That's the way the equipment and software works.

naked female ass only a few feet in front of my face -- with my face quickly gravitating to getting rid of that two-foot distance -- I get a fucking raging hard-on!

My eggplant is conditioned for her response.

...a fine backside is truly a sight to behold, in my opinion. My "strange" reaction is to watching a man work with his hands, or more similarly, recalling having watched it. I was sitting on the sofa in a lovely hotel room at some point watching my gentleman make a martini (without a shaker since I'd somehow forgotten to bring it). Thinking about that instance does something for me...

When I first started seeing my current favorite over a year ago, I found myself getting hard when I saw that she had sent me an email - before I even read it.  

... She has me at full mast and I don't even know who she is.  You are one fortunate dude.
