Come on don't you have any cock care tips? I find it hard to belive you are all shy little virgins!!?
Wash it at least once a day
Wash it if you anticipate a lady going near it
Don't use soap, creams, deoderants, or anything similar
If your foreskin is tight, look up/google ways to loosen it without losing it
Don't be afraid to use tissue - or even wash! - after a wee / wank
Visit the GUM clinic if you're having regular sex with randoms or WGs
Visit the GUM clinic if you notice any odd smells, discharge or lumps/sores
See your GP if you notice any changes (specially if the GUM clinic doesn't diagnose as an STI)
Did I miss anything?
