Movie with all female warriors

Hello Everyone! Im looking for a movie from around the 80's maybe where a man and a woman arrives to an island/cave system where only females living and they only use men to get pregnant. The female warriors catch the guy and they have to fight to have sex with him. Do you know its title maybe? It was kinda strange film, there was a kind of queen who rules over that land, te women wear armor. In the beginning the man was dressed up as the female warriors. Thank you for the help.
