I bought a penis pump because of the LPSG two dollar club. Trying to get credible pics with eight quarters on my dick, every time the quarters got near my dick I lost a half-inch of erection. Another half-inch when the weight of the quarters actually was atop it. Attached is a pic after one of the erection collapses, and during one of the many attempts to get the quarters properly lined up. They kept sliding off one side or the other as the hardon vanished. Had always been curious about pumps. I have plenty of erections and adequate firmness, but they are highly vulnerable to all sorts of distractions/interruptions. Trying to juggle quarters and a camera destroyed about eight hardons in a row before I got the idea to get a pump. The indestructible hardon it would temporarily give would be just the thing to hold up eight quarters! I actually had a long talk with the clerk at the video store about what to get, and ended up with a Doc Johnson manual pump with a squeeze bulb so one hand would be free. Partner was very enthused as he'd tried pumps before and been impressed. No instruction manual was provided but with his guidance I got it in-- and was immediately horrified by the result. Even at the lowest level of vacuum, my semi immediately turned into a painfully engorged erection that looked and felt like it was about to explode. Thinking "this can't be right" I immediately hit the release button so there was no more vacuum. But no matter, my erection was so trapped inside the tube that the hardon did not subside. Could not imagine anyone staying inside such a thing for minutes, as within seconds I wanted OUT NOW. Like there was no low or medium setting and it went right to HIGH. Managed to extricate myself but only VERY painfully as the plastic of the opening was hard and scrapy not soft and gentle like a Fleshlight. Since then have looked online about instructions, and considered trying again in the bathtub. But also feel like some guys might be supersensitive to the effects of even moments of very low-suction pumping, and I should just throw it away. Please advise me before I try again. It didn't leave marks on my dick but even with lube it hurt like HELL getting it out.
