I just started taking Adderall XR last week, got a prescription for 30mg a day. It's going well and good, but the other day I masturbated for 5 hours. It makes it hard to get/maintain a boner and achieve an orgasm, but it also just makes it feel so damn good during the process for some reason. It started hurting a few hours into it, but I just kept going, it was as if there was nothing else to concern myself with... I often times get carried away and determined to finish during those times when it just seems like its not in my stars to do so, but this took it to a whole new level. I have a couple of small scabs, my shoulder hurts like hell when I lift it above beating position, balls hurt, and I feel sick in my stomach as if I'd been punched in the taint about 6,000 times, which is pretty much what happened. Watch out, folks.
I was on adderall a long time ago and never had an issue....But everyone is different. You may want to consult your health care provider. Depending on you age and level of health (if you know what i mean) This will effect you only temporarly. But if you are concerned witch it soulnd like you are...Call your Dr. !!!! Good Luck
