This is embarrassing to ask..... But I'm worried what it is from or what it means. I'm a 25 year old Male, 5'8", 150-160 lbs, haven't been sexually active with anyone in 2 years. I'm circumcised and around the top part of the tip of my penis has occasionally tingled the past couple days. Not for a prolonged period, it's almost like a spasm for a few seconds, but I never experienced that before. Is there anything to be worried about? Thanks for your time and if there's anything else I need to answer or tell, just ask.
