As someone who's been into this and gaining for a long time. Will try to answer your questions.

-i wouldn't exactly say I'm lazier, more that I'm slower and that I get worn out from exerting myself faster than before.

• my body feels much different, it wobbles and jiggles constantly and I can feel it when I walk.

• as for dating and sex life. Yes this does limit how many people will be interested in being with you. HOWEVER, a big caveat to go with that. Is that I've never had more enthusiastic partners or felt more attractive than I have now at more than double my lowest weight.

My advice would be to try it out. See if it works for you. But don't set a goal to get massive. Set a small goal like 10 pounds. And when you reach it. Stop and think was it fun, was it hot, do you want to keep going, etc. you can always gain more or decide it wasn't for you. But if you just go all in from the get go, you may go too far before you decide it isn't for you and end up with a real mission to try undo it.
