You're clearly not just looking to get laid. If so, standards wouldn't be an issue.

Related to 1, if you're just looking to get laid, you have to seriously lower or completely get rid of said standards. I mean, if it's just about sex, any warm body should do.

If you're looking to express yourself in a sex positive way, there's actually a surprising number of groups you can get in contact with. Burning man attendants have been a... reliable... source of people who are willing to explore sexuality. But, there is some groups on meetup.com that are focused on healthy sexuality that might fit your needs. Might not get you laid tonight. But, that's more betting against the house if there's there's an event tonight.

Just go out. If someone doesn't pick you up, then pick up someone that you're feeling some sort of attraction to. If you're just intending to get laid, the worst that can happen is that it doesn't happen.

If that's too much trouble, you know someone you can call. Almost everyone that has more than 7 non family member contacts in their phone knows at least one person that can use for a booty call.

The options for a person is pretty unlimited in a place like Los Angeles. If none of the things I've said have appealed to you, maybe what you're looking for is not a quicky but some sort of human connection and random sex isn't it. Find some other outlet, a hobby, some other group activity, maybe even reach out to a therapist to talk about that void you're trying to satisfy. But, if something like tinder is putting you off, then (at least to me) it's pretty clear that you're not just looking for uncomplicated, unadulterated fucking.
