Is it disrespectful for me to comment about another woman's beauty when with my girlfriend of three months?

Answer 1

Not if you mean it in an immature way. For instance, you could think someone is beautiful, but as long as your not madly in love with them when your dating someone else.

Another point of view

On the other hand, if you've only been dating for three months, talking about another woman's beauty may trigger any underlying insecurity or self-esteem issues she may have. You may want to ask yourself why it's necessary to make such comments to a new girlfriend.

All men look, but the smart ones keep their mouths shut until they know their girlfriend won't feel threatened by casual observations about other women.
