It's rough when you're in a needy phase. It may be worth reducing the number of partners so you have some energy to create a real partnership which requires more effort. I like to break relationships into components. Usually acquaintance/platonic, romantic, and sexual. Each relationship can be any combination. Acquaintanceship is just general hanging out without really caring deeply about the other person. The platonic/friendship part replaces that and tends to be the hardest because it's more about solid connection, really caring what happens to the other person, supporting them and being supported by them when things get difficult as well as enjoying the connection when things are good. This is something I've noticed most cis-men don't have with each other due to societal toxic masculinity.

Romantic is then more about individual acts of romance, planning romantic dates, making out for long periods, that kind of thing. And it requires some level of physical and/or emotional attraction usually and is about fulfilling those kinds of needs over a medium term. It is best when the types of needs of both parties align, so you're fulfilling theirs at the same time they're fulfilling yours.

And sexual is obviously more fleeting and is better with physical attraction and matching needs, but mostly is just about fulfilling very immediate needs.

Each relationship has some combination of those things. But I find that I need at least one with strong platonic connection or I get lonely. That requires energy in both directions over the longterm to work, so it's the most rare. These you really need to nurture as they are the most valuable IMHO, and easiest to lose if you take more than give. Sexual you can find easily in clubs or whatever and can be fleeting, and romantic takes a lot more to find, but tends to be easy and shorter lasting without the platonic.

So dating cis-men tends to lack the platonic part in my experience due to toxic societal norms. So although I'm pan, I also tend not to date cis-men.
