Is it ok to have fun with a 25 year old guy if you're 38?

There's a guy at my work who I've worked with for over a year.

We get along really well & always have a good banter and catch up every now & again.

We had our Christmas party the other night and we had some time to ourselves.

We left together and hung out at his place. We only ended up kissing and I went home after.

We've been messaging eachother since & he wouldn't mind having a bit of fun. I don't want to long term date him.

This is a big age gap, when he met me he thought I was his age & so did other people we work with so I can pull it off.

Does the age gap matter if it's just having fun?
