I'm a 14 year old male and a couple of my friends thought it would be funny to hit me in the testicles when I wasn't expecting it. Over 2 days I received four hits to the area, one which resulted in me having to sit on the ground due to the pain and just one other one that hurt significantly. I'm just a little worried because I usually have a very high libido but since the first blow I received my libido seems to have decreased quite a bit. Is this decrease in my libido related to the hits I received? The pain only lasted for a few minutes, and I don't appear to have any bruising or anything like that and it's not sore now, but I'm still a little concerned. Can anyone help me here?
