What is that sticky stuff you get on your dick after two hours?!
Question: NOT SPERM NOT PEE!
Answers: NOT SPERM NOT PEE!
Are you circumcised or uncircumcised?
To tell simply look down at your penis and see if your head is covered by a layer of skin when it's soft that you can pull back.
If you can pull back skin you're uncircumcised.
If this is the case it's most likely smegma.
be more specific
Could it be liquid from the girl's Virgina after you had sex?
Or maybe you have a STD?
*Sexually Transmitted Disease*
you should visit a doctor.
