Whay do you mean by sexually compatible, like what are you looking for here?

The sexual part of a relationship takes time to develop like any other part of a relationship. Like you're not going to have all the sex you can possibly have with that person the first time you get intimate. More than that you can't really predict the libido which is the more important aspect of what I would consider sexual comparability. Like one person might be intensely sexual at first but then cool down hard later on in the relationship and vice versa.

I don't know man, basically there's a lot going on there and you can't control test it by having a sex a couple times before you fully enter a relationship. So I'm what I'm saying is imo don't get hung up on this sexual comparability part. The person you have the best emotional connection with is the person you'll probably end up having the best sex with in the long run because you'll just work better together in the other aspects of your life.

Put yourself in the other persons position and you'll usually figure out what the moral course of action would be here.
