How to deal going out with multiple girls at once?

I have gone out with multiple girls in the past two weeks even kissing one and I have another date tonight. I’m not used to this kind of attention from woman and dating in general and not sure how to handle it. I’m talking to a couple girls and enjoying figuring out what I like but there’s a weird feeling in my gut that feels like I’m betraying them idk how to describe. Well aware that we don’t owe each other anything and they can very well be going out with others too but I haven’t said to any of them that I have options and going on other dates. I wouldn’t lie if they asked but I’m also not saying anything about it. I think I’m anxious about feeling bad not giving myself to one at a time like I used to and them feeling like a second choice which isn’t my intention I just don’t want to commit to one person if it’s the first date.
