Sex while dating changing things?

So I (33F) am on the apps and have gone on dates over the last years but the way things happened I haven’t hooked up with anyone in over a year when I was last seeing someone more officially.
I’ve recently gone on a couple really good dates with this guy and I think we might hang out at his place this weekend - I’ve tried to tell myself that I don’t want to sleep with him until we have some talk about exclusivity (which it is too early for) just so I don’t overthink about if he’s seeing//sleeping with other people too.
HOWEVER the other (and more h*rny) side of me is like … wellll in the past I’ve hooked up with guys before having that talk and it never made me feel like they became less interested. Maybe they were more interested after??
Anyway so just curious how gen pop feels their feelings change after sex during more casual dating and/or if you’re against it generally?
