I 23F got intimate with a guy 34M from my corporate office building

We work for different companies and would occasionally see each other walking by. The fourth time we saw each other in the elevator, he asked for my number and we’ve been talking on and off since then, for about a month or so. Today, we got intimate and while it was probably one of the best I’ve ever had, a part of me felt guilty. He is an unmarried 34 year old with a 3 year old son (I didn’t know that until he told me), and I, on the other hand, got out of a 2.5 year relationship with my ex 4 months ago. I don’t regret having fun with him, since I felt comfortable doing it with him, I just feel this guilt. I don’t think the age difference really matters but just the fact that I slept with someone nearly 4 months after a serious relationship. Despite everything, it was a really fun night though. Here is my perspective: I’m 23 and just wanted to have fun for the first time after a long time, and I just felt super close with this guy. He truly is a sweet guy tbh. It’s funny because I’m conservative and throughout college, I was always taught that it’s wrong to have fun with other people, and that settling down early with one person is the healthiest thing to do, but honestly, if you only live once, why not have the fun right??? Thoughts?
