So ladies I need some serious honest advice .

After I was sexual active with my boyfriend a friend told me she over heard someone saying he has Herpes so of course I asked him about it because that’s what I should do . But of course he denied it but today (3yrs later) he has left for work I’m laying in his bed I see some vitamins on his dresser so I look at them and it says L-LYSINE (which I never heard of) so I google it .. google says “L-LYSINE is used for preventing and treating cold sores caused by virus called herpes simplex labialis. We have had unprotected sex since forever .. should I be considered?? Could I have it with no outbreak? Someone help please I’m lost
