So I'm not really looking for advice here, just wanted to have a chat with you guys about a certain phenomenon I've experienced.

Have you guys ever noticed that once you get a girlfriend other girls (who shouldn't know about your relationship) just instantly start paying you way more attention sexually?

I first heard about this from my cousin when he started university. He mentioned that he started dating a girl off-campus and girls on-campus, who didn't know about the relationship, started giving him "the look" and flirting when they weren't the day before. I thought he was just playing things up until I had the exact same experience during my university years.

Its like girls have an internal radar that detects claimed men and instantly adds 2 point to their score out of 10.

Its weird and wonderful and wanted to know if anyone else has had experiences like this?

Keep in mind that I'm only referring to girls who shouldn't know you're taken, I understand how social proofing works with those who do know your relationship status.
