OLD is good only for a one night stand. Go out, fck and leave. If you don't do that, a woman will do that for you. Unless you're a top 10 chad with a ton of money, there will always be someone better to play with women's hypergamy.
Basically because in those apps, physical appearance is the most important thing to get a match. We went there for sex. Men and Women.
The best options on OLD is to get tunned to women that recently broke up (very long term relationship). They're not intoxicated to it yet. So, if you were the first you have a better chance.
Women that use it for the long term, become more selective as they would probably have a lot of fixed guys to have sex whenever they want.
So, if you want only sex... Then learning that game could give you some hook ups. What I see here in Brazil is that women are fcking way more than men on those apps and basically all of them doesn't talk about condom when having sex with you. Had one that started to took her clothes off and went upside me like ready to ride, if I didn't stop her and get the condom, she would fck without it. Asked her later if she was taking any pills... She said no (she was 22yrs old). Insane.
Then comes a time that those interactions became not that interesting as before. It's purely something sexual. And to be honest, sometimes I miss feeling that good connection with a woman. So it's not that funny as it used to be for me in the past.
To finish... I think OLD is a good opportunity to realize that. You can have sex, but that horny sex with a hot girl is not that good as our mind fantasizes about it.
