I'm cut/average sized. I have retractile testicles which means that when I get hard, my balls get snuggly pulled up against my body, which in turn means every stroke not only stimulates my cock, but my balls too: it feels amazing. My body is IMPOSSIBLY sensitive (I'm quite ticklish!), for better or worse. Often times when I am trying to fall asleep, my anal muscles and sphincters will twitch and spasm... it feels like butterflies in my stomach... and I can feel my prostate begin to swell. I also have a real problem with sleep where I often wake up with a raging hard on, and find myself jerking off in my sleep!? Sometimes just wiping my ass is hard to do bc of how sensitive my anus can be. If I'm turned on enough I can have multiple (dry) orgasms with my cock, hands-free ejaculation, as well as the male 'super-O' prostate orgasm where you can cum for hours (: I love wearing a butt plug around my apartment while cooking/cleaning. When I'm home alone, I pretty much always have an erection to varying degrees, often leaking precum. I still get spontaneous boners in public, like a teenager. It can be quite distracting!
