I think this woman is being very cruel, she knew it was your first time and should have had more respect for you than that. Especially with her having a hygeine problem.
Had i been her, i have to admit i would not like to be told that downstairs is a bit wiffy but had you given me the same excuse you gave her i would have taken the lead and tried my best to make you feel comfortable.
If you really want this woman then of course you both will have to sort this out, call her and apologise tell her you want to see her again. Theres no use in playing games ive found its better just to be flat out and honest with people. If she refuses then fair enough, youve asked her, she knows how you feel and the ball is in her court and she doesnt sound like the kind of girl whos too shy to ask a guy out. Maybe then after a few weeks you could ask her out again, if again she refuses then leave it and move on.
if she says yes the 1st or 2nd time be prepared to wine and dine her and show her you mean business, although you did nothing wrong she has to build up her confidence and trust in you again. and when the time is right move on to sex, if the same happens, suggest (if appropriate) maybe having a shower together and wask each others bits, there you go, youve washed her you know how clean she is BINGO!!
I hope this is of help to you!!
Good Luck
