Well I personally don't feel that large labia cause bad odor. Just when you wash make sure you clean well in the crevices and folds, ya know? If i know theres a possibility that someone is gonna go down on me, i always wash as close to the time as possible just incase. But, i've had someone go down on me several times unexpectedly when i hadnt recently washed and ive never had any complaints... This sounds gross but if you're really that worried about it.. I suggest doing a quick check before anything goes down by touching yourself in the folds of in between the inner and outer labia.. (thats probly where odor would be first since its the warmest place) If it smells bad on your fingers, its definately going to smell bad in their face. But really there shouldnt be any strong odors down there, If you're having issues with that on a regular basis, i would suggest seing a gynecologist. You can try soaps especially for that, but for me, it just cuases irritation. And as far as being worried about what they're going to think about your labia being large, my only suggestion for that is to do it with someone who is MATURE, and someone who you've known for a while and has respect for you so they have more to base an opinion off of you than just your pussy. Not to mention, theres a good chance he might like your large labia. Again.. that depends a lot on his age and maturity level. Young guys dont seem to understand that there are varieties out there, they think theyre all supposed to look like porn magazines. Idk how old you are.. hopefully at least 17 or so.. otherwise i dont really recommend it at all.. Anyway, good luck
