Bicycling after SRS?

I'm asking this here because I know there are a lot of avid bicyclists here, and maybe one of you has some experience with this.

I had SRS in early February, and I'm now recovered enough that they say I can get on my bicycle. So this morning I tried just getting on and riding around the parking lot, just to verify that I can.

Anyway, I notice that it was uncomfortable around my new vulva -- not, as I would have expected, on the pubic bone. It felt like I was sitting on that area and the tissue was getting pulled in an uncomfortable way.

Is this something that goes away as I recover more? Or is it something I just have to get used to? Or do I need to do something? I'm just worried about doing damage to the newly reconstructed and, I presume, still healing tissue.
