SEX TWICE IN 1 HOUR!? What are your thoughts on this article?

TMI...my husband has always had a strong libido but he has not made it for a round two since we first became sexually active back when we were dating, and don’t get me wrong that has been okay with me. BUT tonight, 20-30 mins after round ☝🏾 he was ready for round peace✌🏾! Lol caught me by surprise and was pretty exciting since it was out of the norm.

We are TTC so I guess my real reason for discussion is because I don’t want to decrease our chances by not letting his “sperm build up” as some believe.

We are doing Letrozole+trigger+timed intercourse and instructed to BD tonight(self-administered shot this morning) 3/31, 4/1, 4/2. Will that “extra BD” tonight hurt our chances of conceiving.
