Rubbing burn 🫣

This question is for all my fellow grinding lovers lol. I started seeing a new girl like a month ago and the sex is so fun, we both like grinding a lot, specifically me being on top. I've been out and dating casually for like 3ish years, but have only had short term hookups so this is new territory for me. After a mega gay weekend long date, I’m sore (to be expected) but also the inner part of my left leg/my labia has like rubbing burn? I'd appreciate any recs on:

• Thigh straps for grinding? maybe not for penetration but to rub on?
• Products to use in the meantime to help heal inner leg rub burn
• Stretches to help lower back lol

I know part of this is just new relationship energy but I'd also appreciate any advice from more seasoned sapphics. TIA!
