Herpes sores on perineum? Suddenly appeared **TW-Picture**

Very long story short I was finally diagnosed with lichen sclerosis last month. Had it 2 years ago and settled but flared up a couple of months ago. That aside. Wednesday night oral sex from partner and full sex. Friday felt a bit sore. Saturday looked and got blisters on my swollen perineum. With partner 7 years. Ex husband 9 years ago had it and I think I got it once way back. Got Aciclovir from private gp call. Just want reassurance it is this?

I don’t think it looks like herpes.
