<human>: Can you summarize the given text in a few sentences?

I (27F) started casually sleeping with a significantly younger guy (22M) a few months ago. Although we mutually agreed in the beginning to keep things low key, he recently told me that he is upset by the idea of me dating other men and is getting very involved. The sex is fantastic (mind-blowing, 1-5 times a day...I think he's thrilled to have found someone with a high sex drive). I find myself spending a ton of time with him (i.e. sleeping together most nights, cooking, doing date things). We have fun and enjoy being around each other, so I don't want to rock the boat unnecessarily.

However, since I just got out of a VERY long relationship (read: almost ten years) I don't feel comfortable making any long term commitments in the near future. Also, because I considered this casual I haven't really evaluated this guy on serious partner qualities (financial stability, life goals, ambition, etc) and have just been enjoying that he is sweet and considerate. Part of me thinks I'm just in denial about what this is anyways, but the short story is that he's a good guy and I don't want to hurt him.

Any of you have experience being the older woman? What were the obstacles, or what issues did you have to consider/overcome to be in a relationship with your younger SO? Was it successful, or was it difficult when (if) things fizzled out?
<bot>: I'm five years older than the guy I'm sleeping with, he's getting attached but I'm not ready for serious relationship.
