+1 for Rich's Custom Seats.The OEM seat design does force your cahones to rest up against the front portion of the seat that resembles a camel hump. My remedy was to get a custom seat that fits my butt, takes pressure off of those sit bones, puts me further back in the seat and did require me to raise the handlebars and set them further towards me. Took the pressure off my jewels and my butt and my wrists. I live relatively close to Rich's Custom Seats in Kingston, WA. and he and his crew do a good job. I've had the seat now for 6 years and I'm very happy since I can experience an all day ride without complaints from my butt or cahones.
I have worn purpose built shorts for many years as ****** tightys did not cut it off road racing. Bicycle tights with foam buttpads increase mileage per day and keep 'the boyz' in place. Chamois leather down there is good as well.
