Most Helpful Guy
Yes this has happened to me also.
It used to happen to me with my really pretty girlfriend and my next grifriend who was not as physically attractive. I had a discussion about this with my guy friends and we came to the conclusion that with the pretty girlfriend girls where admiring or even jealous of her looks. and with my next girlfriend who was not as physically atractive they were prob woundering how we ended up together. That's what I think but I've never asked the opinion from a girl.
