unless there was sores present, you never had a risk.
What about the second question
I know its kind off stupid to ask but.
will his sperm enter my penis and produce more of his sperm in my testicle?
Your body already produces millions and millions of sperm on its own and his dna is different from yours. Sperm is not like a virus or bacteria.
Thank you very much.
So that means whatever is produced its still my sperm with my DNA and not his even though the sperm enter my urthera?
you do not have another man's sperm inside you.
