The male half of a relationship who allows and finds sexual gratification in allowing and even encouraging his female partner to have sex with other men. Not to be confused with the CUCKOLD relationship where the male is typically weak and into humiliation. Stags are dominant but want to share their women.
I met a STAG at the bar who invited me to his home when he noticed his wife checking me out and flirting with me.
