I think that you need more than anything to take control. You need to feel in control of your own body.
(And as for the guys who disappear after sex - as someone else said, that's a million reasons - you can conclude it's the wobbly bits. FGS, it is possible to work out from looking at someone that they've got wobbly bits - they must have known already.)
You need someone who sees you and wants you. And the best way to make sure you really feel good about yourself is to take control of your own body. You need to make small changes that will have big effects.
With your job and children and all, you have a hell of a lot to do, and only so much energy in a day. I totally understand. And I promise you that it is very very easy to do a kind of side-step and change things. (and 14-16 really isn't bad - it could be oh so much worse!! - so it will be relatively easy to improve massively)
My advice is:
Diet
Swimming
Yoga
You can't control the guys, but you can control what you put in your mouth. Eat less. Don't eat sh*t. Drink small cold Evian bottles you keep in the fridge. Eat organic handpicked blueberries. Make everything you put in your body a beautiful thing.
Swim. If you can, every day. Get in the water. Feel your body and how strong it is.
Yoga - this is the easiest. You can do it first thing, or when they're all asleep. Just sink into your own body and feel its power.
You need to remember who you are.
Then you will decide about the guys, and you may not get naked so quick. Wait until they can't live without you. : )
