The relationship is going well, why sabotage it by providing him with information he doesn't need?


I just don't see how telling him could be helpful or beneficial to him or your relationship.


As mentioned above you were broken up, so no need to mention the names of anybody you saw naked as its essentially none of his business.


Sure if he asks about it, don't lie to him, (although I honestly probably would just to avoid unnecessary conflict) but please don't create problems or drama where there is none.


Unless for some reason you are looking to swop lists of partners you each had during the break up...

Which is never a good idea IMO, leave the past where it belongs and focus on the present.
