I generally lean my weight to the front of the saddle and I instruct anybody on a peeing horse to do the same.
I've found that, often times, the beginning type riders I work with will often lean back while the horse pees (since the horse's back is slanting down) which seems to cause the horse to have to work way harder at balancing a rider while being in the peeing stance.
That's why I instruct people to lean forward, then there's no "you can't balance yet, lean forward" and "you can ride well, you don't have to lean forward" and nobody feels put down or embarrassed (beyond the usual "OMG! The horse is peeing! PANIC!!!" lol!).
Another thing is that, with Lacey, sometimes she needs to pee but I'm in the midst of something and need her to be at the ready. Me stopping her and leaning forward kinda her "Here, here's your time to pee, use it" instead of just having her stop whenever to pee. Of course, that's not a cue for most horses but for Lacey, it is.
On other horses, I'll lean forward a bit because most of the time I ride with lesson kids or other people in the learning process and I feel like it's kinda unfair for me to be like "Oh, I don't need to lean forward because I'm 'good' but I don't know about you, so you better lean forward!" haha
If I'm riding by myself, I shift my weight forward but I don't lean forward very much at all. Unless I'm riding Lacey, since it's her cue, but she generally makes sure to get it all out before or after I get on/off.
