Throwaway

So I'm 24 years old and I'm a virgin. I've never even kissed a girl on the lips so I don't really have a lot of experience as to how dating/hooking up works. 

I recently have been trying tinder and bumble to try and get some experience or find someone to be with, (I'm not really sure I'm kinda just winging it). After using the app for about 2 months, I have been on a date with one girl (who admittedly semi catfished me), which we are set to go on another date, and I have another date set up tomorrow with another girl, as I'm texting someone else.

I hear that tinder and bumble are mostly casual but I was wondering by going on dates made it too serious and that I'm playing them? I dont really know if what I'm doing is messed up or not.

Tl;dr: Am I (24/M) the asshole for dating/trying to get with 3 women casually? I haven't lied to anyone but I'm not super experienced on when something is exclusive or not.
