Obviously your PT has no idea how hard or fast or long women ride their bikes for!

Normal for me after a time trial (where I have sat without moving for 35-50 minutes - depending on distance 18-25km) is numbness, awkwardness to walk, vague pins and needles and if I go pee straight away then the area feels a tad uncomfortable. After a tt I often have pain in my lower belly from the muscles - like when you have used muscles you don't usually use and they hurt for a few days. When I have that muscle pain, it hurts a little inside to pee - I guess because I am using the muscles... (also when I coff, sneeze or go up or down stairs)

Normal after a commute (40-50 minutes) to work is little or no discomfort, I just need a stretch and I'm fine. This is probably because i stand up, and shange my sitting position during the ride.

Normal after a long training ride (anything up to 3 hours) is similar to the tt, but without the painful muscles.

Dunno if any of that is useful? Best wishes in making everything fee better.
