First Race Coming Up. Any Advice?

Yeah, you can use a hand on someone's low back/rear to help them across a gap or up a hill in situations where they just need a little extra push to grab a wheel & keep from getting dropped. Depending on body position of the push-ee, sometimes the push-er ends up with their hand smack on the butt.

I actually find this to seldom be true. I have been on many training rides with the guys, and I don't think any of them would be looking for an excuse to "touch your butt". I have been pushed a few times, and have always appreciated it. Take it for what it likely was - a helping hand (sorry for the pun).

If it does bother you, you can just say so.

Agreed. Usually, they will go for the lower back, but depending on the positioning of the both of you and possibly the terrain, placement may be more or less awkward. It is highly unlikely that this was meant in any sort of inappropriate way.
