Hi Luna,
The men who post photos of themselves posing with attractive women on dating apps want to give out the impression that they are desirable to women. They believe that by posting these photos, women that come across their dating profile will look at them as someone worth talking to because they appear to be desirable to other women.
It’s a way for these men to send the message that they have experience with attractive women and attractive women are happy to be around them. The men hope that by posing with attractive women on their photos, they are able to attract more attractive women that are using the dating app.
They want attractive female dating prospects on the dating app to know that they are experienced when it comes to handling attractive women in general and that by liking their dating profile, these attractive female dating prospects are in for a really fun and exciting ride.
