About 3 days ago I masturbated while lying on my side with my legs closed. When I ejaculated I noticed a unfamiliar feeling in my right testicle. I paid it no mind figuring it wasn't serious. Well since then a very slight dull ache there and that my scrotum won't loosen up. Only in a hot bath will it loosen and then only til I'm out and dried. I also can't maintain a erections to orgasm. If I examine my right testicle while in the bath it is sensitive more on the back side. Now I'm feeling a slight dull ache in my lower abdomen. I've read some post's about a few things but the fact my pain started after masturbating has me concerned I may have damaged something. It's seriously affecting my see life considering I can't ejaculate or hold an erection. As a matter of fact it's like I'm experiencing complete lack of feeling and think I'm experiencing penis shrinking. Has anyone ever experienced anything like this?
