I want this so bad...

I am married to a woman and we have been talking for about a year about having another child. Well, today we agreed that we would actually try so we talked to a guy who has been willing to help when we were ready and I had sex with him today. Weird yes but we are both very honest with each other. I told her everything that happened and how I felt before during and after, and I made sure she was ok with it 3 times before we went through with it. I want to have another child so bad that I want this to work the first time. The last time I had sex with a guy was October of 2015. I could really use some positive vibes that this worked and I don’t need to have sex with him again cuz the sex was not as good as I thought it was back in 2015. Lol. And any advice on how to help it stick is greatly appreciated. TIA.
