HSV 2

What are the odds of transmitting HSV 2 to someone if you cover a sore before having sex ? My boyfriend really wants to have sex without a condom but I think I have a sore and don’t want to spread it to him. If I covered it with a bandaid and doubled my meds, the chances would be lower right ? I don’t want to say no to him but I also don’t want to transfer it to him and I really don’t want him to get pissed at me.
