Sex tips or advice.

So my husband and I been together for 10 years. When we first started dating we were 17. We were already sexually active and our hormones were crazy I guess because we did it a lot. .

But, now I have gained a lot of weight and just don’t move the same anymore. He also feels like he puts in all the work or we don’t do it unless he’s ready to go. “You don’t ever come to me, get me ready to have sex”

I need some advice on how to basically please this man on my own. Lol I feel insecure so maybe that’s why? I’m not really good at blow jobs either he says he can tell I’m not into it. He wants “rough” sometimes but idk how to! Ugh I sound lame. Lol

He says he feels he holds back sometimes cause I want “gentle”
