I don't know what's happening to me. I'm feeling hornier for my wife

So I'm a man that has been married for the past 10 years . Me and my wife have had our ups and downsbut we have fought through and we're still together after 10 years. Lately my wife finally is getting an understanding that part of the marriage is to actually have sex because usually one time a week is just stupid for me. But something different has recently changed and I don't know how to really explain it. I've been constantly telling her how she should be letting go and being free and just wild and not thinking because we have so many problems that we always trying to resolve the issue and not really have too much time for ourselves we have date night on Friday but usually gets monotonous because of how tired we are of dealing with everything. I've been on a subscription for us to be able to get more intimate and for her to learn how to be more intimate with me on how to give me a blowjob or how to stroke me or how to do certain things sexually that'll make me hungry for her as well as for me to learn those things as well​. Her favorite position is doggy style but I love looking at her butt but I'm a tits person and I love seeing her reaction of her face how it's hit swing how gorgeous her thighs thick thighs are cuz this is a BBW woman I love and enjoy and ever since I married her saw her I've always felt addicted to how gorgeous her body is completely. However because of the problems we barely had time but as of right now we finally are building a business and making money off of it and now that we're not really fighting for financial problems which was the big thing that was killing sex . She's finally letting go doing this description that I got for her for us to be able to get more closer together and for some reason ever since a week ago she's been a lot more willing to have sex and even want it. She's looking me up three times during the week dressed as things like in sexy lingerie or a schoolgirl or even a goth girl. Because of that I have felt so much more hornier and wanting to have sex with her every single day without stopping. My mind what as far as to fantasize about doing it in public in the beach or even in a nudist resort and even have sex in the pool and we only want to be with each other and even thought of going into one of those sex rooms and leaving the curtain open so that others could watch and another couple can just have sex right beside us and hear moans and screams of everyone but hers would be the best out of all of them. She's not that type of person to be able to have sex with others like that and I also like as being private but for some reason my mind has gone way off and wanting to adventure and have sex with only her everywhere I can because of how incredible amazing and sexy this woman is. I really want to make this woman squirt and yell for me a lot more than she usually does she's learned how to stroke me so greatly she's been better and better and blowjobs and is finally enjoying when I give her oral. She's a gorgeous BBW woman with great big tits thighs a good booty and a gorgeous Latina face that I just can't get enough of. I'm just trying to know what has happened to me if my desire is just grown a lot more for her or was actually just going on cuz I want to continue learning more about sex I want to know how I can do that and do the things like weird different positions how we can satisfy each other more how we can make things more exciting I want to know it all but I just felt like my mind has gone off the deep end with this thinking of wanting to do to have sex and then leaving others to have sex next to us or others watching. I even asked her to be her sex slave for a day and she responded with massage oral and hard doggy. Am I going crazy
