I wouldn't say the rose Yes intimate wash is highly scented, but pleasantly enough to know it's rose & for that reason I preferred it to the unscented at the time I could use either without probs.
Expect you already know Aveeno do a range of washes. The one I use for the intimate area is described on the bottle as "Skin relief body wash. Soothes very dry skin". Yes, it does foam but not excessively, produces an unscented, I'd say silky feeling, light cream wash. The 500ml bottle I buy is oat coloured with a navy lid. It can be hard to find where I live, but I usually manage to get it in Waitrose.
Hope whatever you opt for does the trick for you. Horrible to feel uncomfortable in that area.
