You have biology working against you, because our programming is to spread our seed to as many healthy woman as possible, and their programming is security and a family. Gay guys have it easy in this respect, because most guys are sex pigs and if you're hooking up with other guys you can get multiple partners every single day with no strings attached. And girls are the opposite. What does a lesbian bring to a second date? A U-Haul. Because they move in together.
You can, like others have said, be honest about your intentions and go out there and see who you find who's like-minded. I think you'll find that you can't change human nature, and if you're sensitive about others' feelings, you can end up feeling guilty on a regular basis. But there's nothing that says you can't follow the beat of your own drummer. Maybe you can make it work in your own way.
