herpes 1

i’m hearing different things i just want a true answer and i’ve done all my research and still there isn’t a for sure answer but it be cool to have a nurse or doctor on here to answer this.. so unfortunately i got hsv1 on my lips i shared a vape with someone but anyways. i’ve been having relations with this dude and i feel like i just have to tell him i have a cold sore on my lip and it sucks because i feel like he’s going to cut me off because he gets so disgusted easily bad and i don’t think it’s fake because i didn’t get this sexually… but is this still transferable even after i take the medication and wait.
