my friend’s boobs got bigger after sex

dear heather,
My friend recently lost her virginity, and shortly after her boobs got bigger. She
told me having sex makes your boobs bigger. She said it has something to do with
your hormones. Is it true?

There are a few things that can make your boobs bigger — padded bras, gaining weight, etc — but having sex is not one of them. Yes, your hormones definitely spike up once you begin having sex, but there is no direct correlation between losing your virginity/having sex and breast size.

There is one reason your friend’s boobs may be bigger, though: The Pill. Has she started taking it?  She could’ve just started taking the birth control pill once she started becoming sexually active. Different gURLs have different reactions to various brands of the Pill, and it’s not uncommon for gURLs to gain weight. Some gain it all over, some gain in their face, some gain it in their boobs, and some don’t gain weight at all, but it’s likely that your friend is one of many who gained weight in her boobs.

There’s no real scientific reason for why the pill causes weight gain, except that it fools your body into thinking you’re pregnant so that you can’t get pregnant. But regardless, just let your friend enjoy her new voluptuous curves. And maybe show her my answer and let her know that it’s the Pill, and not the sex, that she has to thank for them.

take care,
heather

    I lost my virginity like few months ago and me and my bf also noticed huge changes in my breast. I had always those small, nonexisting ones and now they are so much bigger. I do NOT take pills so there must be some connection.

    this is true. having sex frequently after couple of day grows breast size, even you’r not pregnent.

    My breasts get bigger whenever my boyfriend and I have a lot of sex. We have difficult schedules so we usually only get to have sex once every couple of days. When we have time off from work, we have sex at least a couple times each day and after the first day of extra sex, I notice that my breasts get full and a little sore. They get smaller when we have less sex.

    I have an IUD so that might have something to do with it. But I did want you to know that I have noticed that my breasts get very full, an entire cup size difference, whenever I have a lot of sex.

      now a days, young girls have big breasts, it do not only depends on the growth of body, but mostly depend on sex. if you don’t have sex, your breasts size increase normaly with age, but if you have frequent sex you can feel your breasts size increasing.

    My breasts got a lot fuller after I started having frequent sex, but that could just be because I was so young and was still growing.
