Down vote away but for me personally, I don't think I would lose attraction because I probably wouldn't be attracted in the first place. I'm not saying people have to be perfect physically and scars and stretch marks don't bother me a bit, but loose skin would absolutely be a turn off for me. I've always been in phenomenal shape and I find that important in a partner, for a more serious relationship I would always worry in the back of mind you maybe would gain the weight back because physical health and fitness haven't always been a priority. I had a good friend in college who had lost weight who I was attracted to in almost all other resoects, but everytime we tried getting physical I just wasn't sexually attracted to him. That said, I bet most or many women don't share that opinion. I can't tell you what or how other women will react. I think your prospects are probably fine and in time the skin will tighten up and you'll be more confident. I also think it depends on what type of woman you go after if you lose weight and then suddenly feel entitled to a girl with a body that's a 9 or 10 you might get rejected more than if you pursue normal women. I have an above average body and every partner I've had has had an above average body too. But it really boils down to individual women. My opinion doesn't matter because I'm probably never going to meet or date you. Sexually every person is turned on or off by so many different things. All that aside, congratulations on losing the weight and I bet things won't be as bad as you think. You arm in all honesty looks fine. My boyfriends arms have stretch marks from weight lifting most people have stretch marks, hell I do, and I've always weighed under 115. Also keep in mind there is no normal human being. I see a lot of naked people in my line of work and everybody honestly usually a few things different about their anatomy.
