Thank you for sharing your review "I told hubs we were switching to protect his swimmers ...": I went for conceive plus for 2 reasons.
1) I could pick it up in my local boots so I did not have to wait for the post!
2) you use it like a normal lube- no applicators or anything that made it feel clinical.
My reasons for using was that we like to use something anyway and heard something about some of them not being good for spermies. I told hubs we were switching to protect his swimmers and we fell that month... we might have done anyway but it might have helped who knows?!
