My urologist, who is bi, makes certain I enjoy my prostate exams. I have them twice a year now, since undergoing brachytherapy for Stage I prostate cancer. Prostate cancer is no longer a problem and I still have a working prostate gland. But now I need a digital check twice a year to check if it's beginning to enlarge (something that happens to most men, prostate cancer or not).
The only problem I have with prostate stimulation is when I DON'T have an erection. So, I work up a semi hard on before The Good Doctor inserts two to three gloved and well-lubed fingers up my ass. He never spends more than 30 seconds to a minute mushing my prostate around which always causes me to produce a partial if not full load, sans orgasm.
If my dick isn't semi hard, the ejaculate tends to clog up in my urethra, making taking a piss later a bit of a challenge (not painful, just messy). With a semi hard on any ejaculate that is produced easily escapes my dick into a handful of tissues I've wrapped around the head of my dick for just that purpose.
I consider myself lucky. Having a bisexual urologist has improved my knowledge of exactly where and how to best stimulate a partner's prostate when fucking, during foreplay, or when my jaw is tired of sucking someone off and I just want them to finally cum.
But I can fully relate to having the sensation that I have to pee during and after a digital exam. I just wish my urologist would let me return the favor. He's a hot DILF in his late 40s who would make a perfect model for that brand of men's shirts where they guy is always wearing an eyepatch. Tasty.
I think i need to go to your doctor!
