Hickey advice

So over Christmas break I have hung out with a friend from college a few times and the most recent time it lead to me getting hickeys all over my chest but we didn’t sleep together, and now a guy that I was going out with in October wants to take me on a date this week but I still have hickeys and knowing how our past dates have gone I don’t want him to be mad. Any tips on how to get them to fade faster or keep my shirt on so he doesn’t get mad?
