My long-term partner and I are having an issue in that for a duration of ~2 weeks after intercourse she experiences vaginal dryness, irritation of the labia major, and an off odor. I've been aware of this issue and we both make sure she's well aroused before attempting to perform any form of penetration. The symptoms seem common enough but the duration of 2 weeks is what's leaving me clueless to the diagnosis.
We were each others firsts, separates for ~3 years (both of us had other partners), and have since spent time with each other again. But it seems this problem did not develop with her other partners. I've ruled out hygiene as I make a deliberate point to wash before intercourse because of her sensitivity (not to say I don't regularly, ew). We've both been checked for STI.
She rules it as a case of mismatched dimensions, but I'm unconvinced.
We've had all combinations of her being on and off BC and my using or not using a condom. The resulting irritation is persistent.
We don't use a lubricating product because she claims it also leaves her with a fishy smell. I feel we should however, is there a sensitive formula anyone can recommend.
I'm a considerate lover and don't think I'm penetrating with excessive force; I love her and don't want to cause her so much pain.
Honestly, I've at a loss for what could be causing THIS MUCH aggravation. I'm desperate and tired from lurking forums looking for similar cases. I'm hoping one of you can help me out, THANKS!
