Hi, I am not trying to hijack this post, so let me know if it's misplaced.
Another option to consider for a laid back gay beachy vacation in Mexico is Zipolite. It's very hippy, laid back, people stay out all night to watch the sunset in the morning, and has nude beaches for gay and straight. Be forewarned though, the accommodations/setting can be a little more rustic, and it's a little bit of a haul to get there (flight to Huatulco and a 1 1/2 hour drive). It's a really beautiful, sexy place to visit if you know what to expect.
