LOL! What revealing responses!

I don't mean I'm actually feeling too much weight/pressure on the girly bits, but I was aware that when my "seat" started hurting, I readjusted myself farther back on the saddle and it all felt fine. What I wasn't sure of is whether that meant I was finally on the seat properly, or I'd just shifted my weight so it felt better (whether it was "correct" or not).

I don't think it's a gel seat -- I'm not getting stuff squishing. I believe the seat is padded but not at all squishy, so I haven't had problems with gel moving around or filling in or whatever.

I need to get measured/fitted/observed by someone who knows what they're doing, I imagine, although I was observed by a guy at REI who adjusted my handlebars but didnt' see any probs with the seat.

Blowing in the tube sounds like the right idea. I'll give that a try!
