This app is all about sex and it brings nude girls and nude women together with guys who want to worship their bodies.Women of all shapes and sizes use the app, so you’ll find someone who fits your fantasies to absolute perfection.All of which is why, one recent Saturday afternoon, I signed up to two websites: Girlfriend Social (girlfriendsocial.com) and Citysocializer (citysocializer.com). You create a profile by uploading a photo, writing a biography and filling in your age and location. You can ‘add’ people who appeal, and send messages inviting them to meet. Relatively new to the UK, ‘friendship dating’ is all the rage in the US. As we grow up and settle into routines, opportunities to meet new people become scarcer.
