“I have resumed sleeping in a “chastity cup” at night. I found that by first putting on a pair of cotton boxer-briefs and then the cup, it helps to avoid the irritation I have been experiencing. I’ll continue and move-on from here. My favorite cup is the XO ProCup with SmartFit supporter. It fits just-right and has a little bit of “give” to accommodate my night-time erections.

I have begun to (internally) call these cups “masturbation shields” for a couple of reasons. First, when the night-time erections come (and they come-on strong), my urge while squirming in the cup is to ejaculate at all costs. That slight “tickle” on my cock’s frenulum can send me into an erotic orbit! Hence, the cup is my “masturbation shield” and is very effective. It will take me to the edge of ejaculation but not beyond. So far, I have not ejaculated into it (but came so-close). Call it almost a “wet dream” while awake…..

I began to dwell more on this……When the male gets sufficiently aroused, his thought process tends towards completing the sex act (i.e., ejaculating) and nothing else! Why is this? I think it is hard-wired into our male brains. As males, we need to be “ready and able” with very short notice. Hence, we healthy males all get aroused, get an erection and have an ejaculation in a short period of time if we want. But for those occasions where the build-up can be longer (for me, while wearing a masturbation shield) it is an agonizing pleasure that I don’t want to stop. And since these erections (and arousal) can last about a half-hour or more, that time can seem like forever.
Funny, though, how all this stimulation does not seem to induce “blue-balls” in me. So I’ll keep on wearing my masturbation shields!
PS I notice (obviously) that when I surpass Day 4 and beyond of semen retention, my erections and my mental state become more arousing, and each succeeding day (I am now into Day 5) only ramps-up the agony until it is time for another release (a ruined orgasm is nice!) I don’t really want to ejaculate but, for me anything beyond Day 8+ in SR is a risky proposition!
