I found myself frustrated that when I searched for "men" in dating and I couldn't tell who was gay and who was straight.

You may validly point out that there is a "gay" category to choose. But most men using the site won't choose that option when setting up their profile. They will most likely choose "male" like they do on all their other surveys and forms. They check "male" or "man". So the majority of male users whether gay or straight will skew towards identifying as man. This places them all in the same output page when you're looking for a man. It's very confusing and frustrating for the user.

The issue arises from the fact that the terms "gay" and "man" are not mutually exclusive. They are not even in the same category. One is a gender, the other is a sexual identity.

My suggestion is to add two more identifiers to the search bar. In addition to age, gender, location, there should be sexuality. A user can opt to say that they are "interested in females" but their profiles are not searchable based on that.

Adding a sexuality filter will allow people to connect more easily with those who share their interests.

Another filter would be sexual preference or sexual position or something of that nature. For example a gay man who is a top would be looking for a bottom or a verse. But when you search "gay" or "man" in the dating section, you find a mixture of both bottoms and tops and it makes things messy and annoying. There's no doubt that fixing this minor problem would benefit a lot of your user base. And it could be the solution to the craigslist personals ad being shut down thereby increasing your user numbers exponentially.

So in summary, in addition to the current filters for dating searches: age, race, gender, location, please add a filter for sexuality and sexual position or sexual preference. It would make things a whole lot smoother.
