I’ve been seeing/talking someone for a couple months. At first it was casual but now it’s moved on to something a lot more. They aren’t in the same city as me at the moment but they’re planning to move in a few months to be with me. Before they left we spent a lot of time together have had sex a few times (with protection). I’m wondering how I tell them I have herpes (hsv1 on my genitals). Is it best to tell them before they move?
I know I’ve fucked up by not disclosing it beforehand. I am so afraid of rejection and I really care for this person.
