European Resort Suggestions

Hi guys. Myself and my partner are looking to go away for a weekend throughout the summer for some "fun". We are looking for a nice holiday location but with sex in high demand. (Swinging) we are not swingers ourselves per say but we will be looking for single men (MFM). Any suggestions? Europe only. We do know of Cap d'Agde but not sure if that is a nice "holiday" spot other than nudity and sex. We do want just a nice place to visit but with the swinger and sex culture
