Hello everyone. I [22M] am not a religious person, but my parents are Christian and we had a conversation about premarital sex recently. I've been single most of my life and they said I come come back to our Baptist church and that they think it's a good place to meet girls. I told them this would be a bad idea, primarily because I am not religious, but also because many of these girls want to wait until marriage to have sex, and I do not want that in a relationship. They said it would be fine and reminded me they waited till marriage. I told them I don't believe in this because if you wait until marriage you won't know if you're sexually compatible with your partner. They didn't really have a response to this, and after I said this we kind of just started talking about other things.

It kind of got me thinking though, how do couples who wait until marriage figure this stuff out? I've been on reddit a while and witnessed many real life relationships, so I know that sexual incompatibility leads to many failures in marriages and relationships. The reason I ask this is because, without going into NSFW content, I'll just say I'm into some really kinky stuff. If I had a girlfriend who wanted to wait until marriage, how are we supposed to know if we will mesh well together sexually? How can you know if you and your partner will have a healthy sex life if you don't even have sex before marriage? I know you could obviously talk about sex before hand, but you only get part of the picture with talking. I think if I got married to a girl who didn't mesh well with me sexually, the marriage would be doomed to fail. I know couples can work on it and try to be more compromising with their partners, but they're is only so much you can do. I don't feel like what I'm asking is too crazy. I mean my parents and grandparents waited, and they are still married for 26 and 51 years respectively. How do you guys who wait do it?

TL;DR If you and your partner decide to wait till marriage to have sex, how do you know if you'll be sexually compatible?
