I've started Ritalin as a 41 year old man maybe a month or two ago. In the same period I've noticed that I am coming a LOT.

Previously I'd say I was ejaculating a normal amount of semen, but now it just seems to keep going and going a borderline alarming amount - easily 4-5 times the previous amount, enough that my wife has complained about it. I seem to have a lot more pre-cum than usual too.

I haven't changed anything else in the same time frame, eg. diet, but I haven't seen this listed in the side effects or been able to find people mentioning it online.

My questions are: 1. Is this a known side effect? 2. Is it anything to worry about? 3. If it's not the ritalin, is there something else that could be causing it?
