I really like when women find me attractive even though I have a girlfriend.
Why does it make you happy if these women flirt with you?
I feel that they are very interesting women, who are willing to talk with strangers.
I can understand your feelings on this matter. It's understandable to be happy when other people find you attractive. Your ego gets a boost and it is okay as long as you don't do anything about it.
Yup, I enjoyed that.
As long as you don't act on it it is a good little ego boost. You should make sure your girlfriend is ok with is so she doesn't get upset.
