Help?

This cycle we are doing BD every other day until positive opk, but i was curious on the days we do BD is okay to do it more then once? I’ve seen people say only once on those days, and on the positive OPK days. But my husband is so horny (me as well) i don’t think once on those days will cut it, as he struggles not to have sex every single day lol. Obviously anything to get our baby, but this is why i was wondering.
