Answer:
I kinda recently lost my virginity to my boyfriend,
in October actually,
and there have been some small changes.
One of the sucky ones is that I started cramping really bad when I got my period when, before, I never had pain.
But, yea, I think I have developed some.
Then again, that could just be the natural course of things.
yea it is possible. But its start when you get your period for some. but yea i think its true.
after you start having sex,your mind becomes more peaceful and your body starts putting on weight.
No! your body will change and develop as you get older. Having sex or not having sex will not change your body shape. You didn't say how old you are but you shouldn't be listening to everyone who tells you stuff.
