Women and men have different standards when it comes to looks. Change how you look. By that I mean, stare at the women like you are not here to fuck, you are here to fuck her. You are dedicated to making her cum. You love her. Women notice these kinds of things. Some of them are so accurate they were literally reading my mind word to word meanwhile some of them were just reflecting their insecurities.
Don't worry, they are thinking about someone else too. The longer the relationship, the bigger chance it happens. Sometimes it's just a person passing from a street, sometimes it is someone you know, most of the times a celebrity and if they are weird enough, some fictional character. Treat them how you would treat JO to make it fair.
Proffessional prostitutes are cleaner, take care of themselves better, are dedicated to make you cum. If you are going to be selfish, choose a prostitute and dont be a regret in a girls life. Either fuck them or make love together. Using them as a cum dumpster is more disrespectful.
