Is this causing any problems for you right now? Are you worried you aren't able to differentiate between people you could potentially fall in love with and those you can't? Or that you can't keep pace with other peoples' feelings? Or just that you're incapable of feeling it again? That last worry is nonsense, the others are real issues that might crop up but that you can work with. The important thing is not to psych yourself out before you're actually having problems.

On a first or so date I can feel enthusiastic about the person. I like them a lot, I smile when I think of them, I'm attracted to them and want to be around them. So I don't have trouble figuring out who to date.

But once we start dating proper, I usually move more slowly romantically than my partner unless we were friends for a long time before. It makes things kind of tough on OkCupid because there's an expectation of immediately getting on the road to coupledom, but I find that people who care about me are willing to work with me on it. I'm unsure about whether I want to get serious with them for a long time, I'm still a little wary of them and their feelings, and it takes me longer to fall in love.

I deal with it by straight up telling them "I'm really enjoying what we have but I move kind of slowly romantically, is that ok?" when appropriate. I try to make sure I tell them nice, true things, even if I can't honestly say I love them back yet. I communicate about my boundaries but stay away from acting like it's a bad thing if they want to move faster, and I try and make sure they're comfortable telling me about what they need. It's often a small source of tension in my relationships, but rarely a cause for breakups, and we usually manage to make it work until either my feelings catch up to theirs or the relationship ends for some other reason.
