I made out with a guy a few days after i got out of a relationship, am I moving too fast?

A few days ago, me and my boyfriend broke up. It was a long time coming and we tried to stay together but in the end it was mutual. We were together a year and a half, a half of that was long distance.

Tonight was my first time going out without being in a relationship and a friend knowing I was single set me up with a guy. We ended up talking most the night and making out (nothing more).

Should I feel guilty for doing this? I was raised in always being in long term dedicated relationships but have never had a one time thing with someone. Am I moving too fast?
