Gay partners which was a site for gay males is unfortunately closed. However, don't be too sad because all of the members that were on GayPartners.com are now moved over to it's sister site UpForIt.com.
Up For It is a site for finding casual relationships, local hookups and sex partners. You can sign up for a free account and take a look at what kind of members they have.
This site is part of a network of sites so they do have quite a large member base which is a big plus. Thats more people to interact with and less complaints of fake profiles or flaky people.
We liked the glossy, image dominant site which has a very sexy, sleek interface.
They had a good, feature rich mobile site and mobile experience which was a big plus compared to other sites in this space. Others appear lazy and uninspired. Up For It does a really good job with mobile for those of you that spend most of your time on mobile.
