The mind is very powerful, never underestimate it. I think these "symptoms" are more of anxiety/guilt.
What could be causing these symptoms then? Imagination? Seems a stretch.
Stop taking medicaine, stop worrying. Masterbation is no risk.
BTW... I know this is bad, but I self prescribed some meds - my kid had it for acne. Solodyn = Minocycline. Been taking it about 3 days. Will that help. Internet said it was good for UTI and clamidia.
