Bro, there was so much unprotected sex with the aim of reproduction that I became physically and sexually burnt out by the time we achieved it. My wife and I didn’t have sex again until my daughter was like 10 months old, and it the frequency only began to normalize over the course of another year or so. I remember we were worried for a bit that it was a bad sign for our marriage or something, but then suddenly my daughter started sleeping through the night and my wife and I started banging again. Completely restored my sex drive. I’m certainly not fucking like I’m in my twenties anymore, but I’m relieved that unprotected sex with the aim of reproduction didn’t permanently kill my boner.
