geez, never never never use a guys narrow seat. it doesn't matter,if you are a slim lady either. i weigh between 117 and 120 usually. but i think it does have to do with the angle of the seat also, because this bike i have now, is a mountain bike but an elongated kind, with the low back tire, instead of the typical . so the seat is differently angled. anyhow, after riding, i came home and got ready to shower and there was something nearly the size of a ping pong ball, in the labia on one side. right in the spot where the soft tissue is behind the pelvic bone. that is the place that is on the outside of the seat. the pressure of the body weight caused a bartholins gland cyst. now its the size of an olive after two weeks. deep inside, and i don't want to mess with it because i read all that stuff about how painful it is to get surgical or drainage treatment. i have not been sexually active long before this and after, so it is not from sex. ( a sex diet, no special guy in my life, you know the old song), will the cyst go away on its own if i use some hot and or warm compresses?
