Hi Ronnie, we are busy ttc, Ive always read that every other day is the best approach although if you think you are headed towards ov maybe increase to every other day but sperm last around 5 days or so meaning you can have sex every other day and get two or three lots of the swimmers up there waiting for the golden egg to come out. There is a channel four programme called 'the great sperm race', should be able to get it on 4oD. Well worth a watch, very informative and if nothing else is a giggle seeing humans dressed up as sperm :)
Good luck! oh and is that you on your profile? if so your pole is going very well!
