Im post many years. Ive found that over time, especialy if your sexualy active, that odor will develop. as was said in an earlier post, " when you can smell yourself just setting there" somethiong needs to be done.
A rule of thumb even for genetic females, is " less is better". try just a clean water rinse first. im thinling about 80% of the time, that is all I need. If that does not do the trick, I lean toward the saline rinse. Im not partial to that vinegar smell. The last thing you want to do, without a doctors recomendation, is to use really strong solutions that will eradicate the natural bacteria that are good for you, and are suposed to be there.
if you are still dialiating, be sure that between each session, you fully clean the dialiator. that is a major cause of bad bacteria and odor.
A trick ive learned over all these years, is to stay dry. cotton panties or cotton liner areas are a biggie. also, in really hot and humid weather, i am not adverse to a dab of baby oil or vasaline, to protect the skin from moisture irratation. it works on babies, it works for me.
recent post ops absolutly should follow the doctors orders.
