[|Human|] how long does sperm stay in the penis when ejaculating twice?well the other day i was masturbating and i ejaculated and right after i ejaculated i started to masturbate again then i ejaculated again so my question is since i ejaculated twice how long does the remaining sperm stay in your penis?
[|AI|]  Hi, Thanks for writing in. The penis contains a long thin tube called the urethra. The semen passes through the urethra and is ejected out of the penis. The sperm can get stuck in small amount within the urethra and this can stay for about 15 minutes. After that the sperm again gets liquefied and comes out during the next act of urination.Therefore, if you ejaculated twice in succession then the semen would have been in the penis for 15 minutes, and then it gets dissolved and is passed out in urine. Please do not worry.
