Being 110 lbs lighter now I will be adamant... There will be loose skin and saggy boobs but...
It seems men don't care. Especially boyfriends that are in love, and especially if you don't let the whole loose skin issue affect you to the point you become paranoid. I think men are mostly put off when we act hysterical and not letting them see our body during intimate time.
I always acted around my ex-boyfriend like I was freaking Miss Universe during intimate time. I didn't turn off the lights or did not let him touch him because I was wobbly (and I am wobblier that jelly btw
). I just enjoyed our time together. And you know what? He found it incredibly sexy and irresistible.
As for what you can do.. well exercising helps to reduce the effects of the weight-loss so do exercise and things will all go for the best.
