Gravel rash is a term used in the gay community, to describe their first anal sex experience, as often the sphincter is very tight, and may produce a rash on the tip and shaft of the erect penis.
Trent: "Man, my first anal sex with a guy gave me the biggest gravel rash on my fucken knob aye! Luckily with time, the wounds have healed and so has my gay sex life!"
