Is it normal that i like to kiss people and have no feelings for

A few years ago I kissed a male friend and it was nice but I haven't seen him in a while. About two two years ago I kissed another man who I didn't expect to end up working at the same place has he works. He still says he likes me but I kind of froze up because I completely forgot who he was. Somedays I don't mind that guy I work with but other days I get feel shy and uncertain if I should to continue being sexually involved with him. I almost slept with in because my car was broken down and after offering me a ride home he said he wanted sex. But I ended up calling a taxi home because we were off work at different times.

On another thought kissing people because I'm bored got me into trouble at a previous job. A man who I didn't have feelings for wanted a relationship and later turned into a psycho after he found out I slept with other people.
