I need major advice regarding being involved with guys from a dating app

So I'm a young single mom and I've recently used a dating app to meet new people. my question is I've met some of the guys and they gotten my attention, where I want to be more than friends. some are a single parent too, is it okay that I've taken more serious steps with them like sexually but obviously protection was used. my best friends are really conserned for me, because the guys are random people yes but I like them I don't know what to do please help. Sorry for the long rant I just need advice or someone to talk to about this I would appreciate it
