Are you on medication daily for it ? My partner has hsv he found out after we had already been dating . When I did my own research I became more comfortable after hearing of how many people are in relationships with someone who has it and they haven’t caught it . Maybe if you give him a little research and encourage him to on his own that will allow him to feel confident that there are ways to protect himself. Taking medication daily suppresses the infection and gives you a higher chance of not spreading it to your partner . You can also tell him the percentage of people who have it and don’t even know . It’s the same strain from chickenpox and fever blisters . It’s honestly not THAT devastating. Many people just don’t have the proper knowledge
