When Erin and I are out, she'll point out the hot people to me, and I do the same with her. She might say, "Damn! Check her
out." Reacting negatively to this sort of thing is just a self-esteem issue.
You might want to intend a girlfried with higher self-esteem who doesn't have jealousy issues... or just keep looking at other women until she's ready to deal with them.
You don't have to poke your eyes out to maintain a relationship, unless you want to date one of the Three Stooges.
