What kind of activities or communities should I go so that I can meet more people, know more people and potentially meet my other half?

Dating apps doesn't seemed to work for me, I'm always genuine, you could say I'm a super straight guy. Plus I'm kinda scared of some weirdly enthusiastic girls from China which feels like a scam to me. So I've never met them irl.
For locals,I can understand there are tons of guys getting matched with them no problem, but maybe because of that the girls felt tired of all the bs they have to go through lol.

I'm thinking of joining some sort of sport. Maybe go to church?
I'm definitely an introvert, cause it always felt scary to me when people are overly enthusiastic haha.

Well, that's why I wanna get tested and confirm that I'm clear.

Edit: I don't wanna be that idiot that don't care about other people's well being. Fyi if U read through my post, I did mentioned that I had 1 unprotected "exercise" long long time ago.
And fyi I did not claim that I have STD. Test still ongoing. It's clear that you did not read the whole story.
