I've only been here a month and have had nothing but positive experiences. No, I don't have many follows yet, but I think that will change if I stay active. The people I've interacted with have been very helpful and excepting.
As for the hooking up, I don't think that is the purpose of the site. Yes, I sure it happens, we do talk about sex allot, but the people are all over the world. If your here to find someone, you better be ready to play the long game. Get to know them, gain their respective and friendship, then if they live near by or are on vacation/business trip in the same town see if they want to meet for a drink. If your look for something quick, hit the gym everyday for 6 months then try Tinder. Good luck.
