If you are really concerned about this issue, I would suggest that you find a saddle that does not allow for pressure on the perimeum. You may have to spend some money on one, but it is worth it if it relieves your anxiety about this issue. Depending on where you live, there are many LBSs that allow you to try different saddles until you find one that you like. What I wouldn't use are saddles that are overly padded with gel. Gel disperses when you sit on it and takes the course of least resistance, usually toward the nose of the saddle and the area that you are mostly concerned about.
