It would be helpful to have a simple toggle that can be turned on or off if you're actively looking for “right now,” as well as an icon like a little house that indicates you can host and a walking character icon if you cannot. Turning the feature “on” could either highlight your profile in the cascade or add a symbol like a flame next to your display name.
(Some profiles say they are “Looking For: Right Now” in their profile but may not actually mean it, so this would help with that.)

Create a section for men who want to date and hang out without the immediate hook up expectation!

Even if it’s a hookup, most times you are going to want something to talk about before you unzip. Profiles are always loaded with user’s ridiculously rules, qualifications and expectations. Having a place to connect with someone on the basis of sports, education, jobs, interest would be a plus

Enable users to identify their personality type, such as out-going, introverted, boisterous, shy, easy going, caring, genuine, happy etc.
