Let me quickly say, the more you are within the "norm", the more prone you are to have your heart broken.
Many women/girls think that the more guys that they can atract, the better...
But it only shows while your "pulling" number increases and your ego is polished, it just means you are failing each and every time to sucessfully maintain ONE relationship in the long term.
So I would be very careful what you wish for, and this is a friendly advice from a guy who more than once was made a shoulder to cry on from friends who thought being slim would make them happier.
Well, it doesnt make you happier, it makes you healthier.
If you still have underlying personality, character and emotional problems, being slim will not be your ticket to happiness.
Yes, you might get more attention from males and temporarely gain a boost for your ego with a "I feel sexy now!" type of feeling, but soon you will realise that by becoming what the vast majority of women let themselves to be, you will become a number in some guys "Score diary" and then the feeling of being used will dawn on you.
Being big sometimes acts as a filter, to filter out the idiot guys who use women for their own egoistic and evil intentions, thats why I get worried when the first thing I see from someone who is losing weight is that they want to be sexier.
Let the guy fall in love with YOU, not because of your body!
If you dont feel sexier now, you should because you are beautiful the way you are and who you are is neither thin or big, your heart is just one size.
I am sorry if I seem harsh on my words, but I genuinely mean wish you well.
