I joined Gay-Boyfriend. C0m a few months ago and now I am pretty convinced by the so called "Best Gay Dating Site"... well, of all: I am not sure if it is really the "Best Gay Dating Site" but sure it is one of the better ones I tested.
Joining is free but be aware: Gold Membership costs (However, they offer special promotion sometimes, special discount, and also free TRIAL membership, and even if not, the costs are more than fair). However, I joined but it took me a while to find soem good dating options. I guess it is like in real life, you need to invest some times to meet "Mr. Right". It worked out for me, pretty happy.
CONS? YES! Some profiles don't seem to be "active" so the admins should do some cleaning. AND: The customer suppoert is not the fastest. Had some technical problems and took forever for them to get it fixed.
