Flacid penis from prostate stimulation?
My friend seems to really enjoy anal stimulation. Giving it AND reecieving it. After some research on my part, I decided to find and massage/stimulate his prostate gland during sex. He said he felt like he was having an orgasm the whole time I was doing the massage but he did not ejaculate. Also his penis became/was flacid during. Even though he expressed to me that he was still turned on and didn't want to stop having sex with me, it was some time and not without some work on my part before he regained an erection. Is this normal?
