<s>[INST] Im a 12 year old male and I started to masturbate maybe, 2 months ago? And last week I did it like 5 day in a row. And quite but when I do get my orgasm my penis goes in and out, then semen comes out. No sperm, am I fine? PLEASE ANSWER QUICK I AM SO NERVOUS [/INST] Dear serve understand your concerns went through your details. There is no need to panic. You are just 12. The pumping motion of the penis and the climax do create a small pulsating sensation to the penis which you are describing as "in and out". That is normal and do not panic.
