This is not uncommon for beginners I reckon. Obvious strategy is to ease yourself into it.
- Make sure you are horny when you post the pic. Easier to get it posted.
- You might want to start at places where such pics are socially expected, and places that are restricted to a limited membership. Some examples include alternative dating sites, here, or some other adult-oriented photo sites. Start with quieter communities and try to convince yourself that no one will see them even if you keep them up.
- Try to set conditions of release and adhere to them. Some conditions might be time frame, number of comments, number of views... etc. This does take strong resolve though.
- You might also want to consider providing others with the control of deleting photos. Exposure blogs, dare sites like GD and OSA, or those who like exposing people here (jennifer_mc comes to mind...) might work. Since it seems like you actually do post photos, this might be the solution to keeping them online. You can't just click delete to remove them.
- Or... if you really want to be "out there", go cam on chaturbate for a few times within a short period. Do whatever you could to gain more viewers (and higher ranking). Chaturbate shows are screen-captured by CB for affiliates' promotion, as well as archived by other third-parties. Once you get used to it, you will man-up. (pun-intended)
Anyhow, enjoy, have fun, and stay safe.
