CBD is both an analgesic as well as an anti inflammatory and it does help relax the body. That said, there are not topicals or products that I am aware of that are CBD only that enhance the sexual experience. Foria Pleasure or Herba Buena’s Quiver are two topicals that are THC based but do not get you high. There are also a variety of low dose edibles that may enhance your experience but may have you feeling relaxed and not stoned. My favorite is by Satori-their wild strawberries covered in chocolate.
This represents my opinion and experience only. I hope this helps!
