Look at what others post and try to create something different. I mean, if you want to be noticed you should not try to look like everyone else.
I would suggest outdoors pics where you put your camera/phone on a chair or something. Then put it to record VIDEO. Pose in front of it, make different poses.
Then load the video into your computer and extract a frame where you look like you want. You know, a video is 25 still images per second. Every frame is a potential picture.
And please, don't post a closeup of your penis only. They are sooo boring and just shows that you have no idea what kind of picture a woman likes. We do not prefer closeups. We need to see more of the "package".
Closeups are something that men like to watch... so in short: If you post a closeup of your genetalia, you are really mostly only talking to the male audience, the gay audience.
Would you like that? ;-)
