Can the vaginal pH irritate a partner member during intercourse?

Hi I have a question. Can vaginal ph irritate a partner member during co-operation, which also makes me because of the fact that he appears through my ph? From time to time after co-operation, red swedzace spots appear in the boy and in me itching and burning with white uplawami which usually lasts 2 days and stops flying. I was at the gynecologist who during the examination said that I do not have any changes that there is only irritation and redness of the vagina proper secretion but I do not have a fungal infection and I do not have to be afraid of anything I can be calm, because while watching he would notice that there is ringworm, that he would recognize fungal changes. Only with the worry I am about these symptoms. Condoms do not use so allergy to condoms falls off. We use mucovagin moisturizing gel, but we have been using it for a long time and nothing happens. It was only at the last time that the symptoms appeared. We wash with provag liquid both. I have no idea where to look for the cause. Bacterial inflammation also exclude because there is no smell of fish would recognize by the smell because I once had. Only once I was found to have bacteria but ecoli which apparently does not heal because it does not give symptoms. What could be the reason because I have no idea anymore? Is it the ph of my vagina that can give such symptoms
