Hi everyone

I am experiencing chafing in my upper leg area (crotch) and also under my butt cheeks. It's around the outside where my panty line is (I do not wear panties under my shorts). I have no sit bone pressure and no soft tissue pressure so very happy in those areas. I have tried Chamois Butt'r but it doesn't seem to help.

From my searches on this site I'm getting that I may require a T shaped seat instead of a pear shaped seat. I currently have 2 seats in my possession, a Specialized Lithia Gel and the Ruby Gel. Both are 155 and I was measured at 131. I am having the issue with both seats. Is it likely that I need a different shaped seat or could it be something else?
