This morning, I went to the medical clinic for my regular biweekly testosterone injection. I always enjoy dropping my pants and underwear for the nurse. She's a pretty lady, about forty, who's always friendly and seems to enjoy me visiting her. This morning, before I went, I showered and got everything nice and clean, and shaved my pubic region, my balls, and the base of my cock so it was all nicely exposed. Then, while I sat at the computer and watched some porn, I used my power vacuum pump to get my cock as pumped up as I could. I took 100 mg of viagra so that I'd be at my best, and when I took my cock out of the pump, I teased my foreskin back so my glans stayed exposed. When I got to the clinic and went to the nurse's office, she told me which side she'd be injecting (alternates each time) and I dropped my pants and underwear and chatted with her while she prepared the injection and got a bandaid ready. I made sure I did some kegal flexes to be sure my cock was as big as possible without being erect, and thoroughly enjoyed her giving me the shot. The injection is fairly slow because the testosterone is thick, so it takes a little longer, and then I have to wait for her to apply the bandaid. My cock felt like it was throbbing, and I realized when I started to dress that there was a drop of precum drooling from my glans. It's one of my favorite medical experiences, and as soon as I got home, I got naked and went to the computer to jerk off while I enjoy the fantasy of what's happened. I wish I could find a reason to do it more often.
