I'm a 52 year old, 6'4" 365 lbs married man, and I'm a chubby chaser

I'm not really sure why I'm posting this so I suppose it'll be interesting either way. <br><br>I'm 52 years old, 6'4" 365 lbs, and I'm married and my wife is a few years younger than me and unfortunately, a lot smaller than me. We were married almost 11 years ago, but have been together for over 20 years. My wife has a daughter from a previous relationship and I have two daughters from a previous relationship and we also have a daughter together. <br><br>For a long time, I've always been attracted to women who were bigger. I remember in school there was a girl who was a little bigger and I was always so interested in her and thought she was so cute, but I never wanted to approach her. To be fair, I was a lazy kid and didn't date much until I was in college. <br><br>Throughout college, despite my preference for chubbier women, I always dated women who were smaller. For whatever reason, I always found myself more comfortable around those women. I know now it's because I was afraid of rejection so I figured it was safer to go after who I thought were more attractive and that's how I met my wife. <br><br>I knew my wife and her daughter for a while before I dated her. She's smart, funny, and beautiful, and I couldn't help but be attracted to her. I was still pretty young at the time and I didn't realize that if I got involved romantically with her, it would mean I would also be getting involved with her daughter. My wife was a very young mother, and her and her daughter were more like sisters. <br><br>I dated my wife, and everything was great, but the more we got to know each other, the more I learned about her daughter. My wife and her daughter were very similar, had many of the same interests, so they were very close. I learned my wife's daughter and I had a lot in common, and I really enjoyed spending time with her. After I got to know her more, I finally realized that I was in love with her. I had never felt so deeply for anyone in my life. I told my wife and she was also in love with me. <br><br>We dated for several years and then got married. My wife had another child a few years later. My wife's daughter got married a couple years after we did, and I was so happy for her. She still lives close by so we see her a lot. Less than a year after her wedding, she had a baby girl. Her and her husband are my son and daughter-in-law. <br><br>After my wife and I had our daughter, I started to gain weight. I always had a bit of a belly, but I was never really fat until I was in my 30's. I'm 52 now, and I'm almost 370 lbs, but I'm happy and healthy. I thought about losing weight, but I have so much pain in my back and legs that it's hard for me to do much exercise. I also have a lot of pain in my knees so it's hard to be on them, which makes it hard to do anything that requires being on my hands and knees, like housework or gardening. I've had heart problems and a heart attack, and I thought about losing weight to improve my health. <br><br>I do yoga almost every morning and I thought about getting into Pilates, but I'm afraid my back might give out. A few years ago, I tried to lose weight and I got down to 320 lbs, but I was working out a lot and then my back went out and I gained almost 20 lbs while my back and legs healed. <br><br>I've been lazy for a while now, and I'm starting to think about losing weight again. My wife and I have been talking about going on a cruise in a few years. It'll be our first time and my wife and daughter have never been on a cruise. My wife, my daughter, and her husband and son will be going with us, and my wife said that if I wanted to go that I would need to lose a lot of weight. She said there were a lot of stairs on the cruise ship and I'm not healthy and strong enough to climb all those stairs. <br><br>I know yoga is very good for my back, but I'm afraid if I exercise too much, my back and legs will give out. I'm considering moving into water aerobics, Pilates, and swimming. I've done Pilates before and it made me very limber. I have a lot of pain in my knees so it hurts to walk on them, and I'm considering getting knee replacements. <br><br>I'm not sure what I should do. I want to go on the cruise, but I'm afraid of exercising too much and getting hurt. Does anyone know good exercises for losing weight with back and knee pain? <br><br>TLDR: I'm a 52 year old 365 lbs man who is a chubby chaser. I want to lose weight but I have back and knee pain so I can't exercise much. Any advice for how I should lose weight?
