Brother will not get pregnant
Sister can

I have 3 daughters. I want them all to have fulfilling sex lives, whether that means the one from first to last, or a different man every day or even gang bangs, as long as my girls enjoy it I'm happy.

Probably because fathers know exactly what teenage boys are capable of since they were the same age. I don't think dating is a problem, but teenagers do not need to engage in sexual activities. Not because they aren't enjoyable mind you, but because they generally aren't mature enough to deal with the responsibility of raising children because they are in fact, still children themselves. Dating should be fine, but teenage boys have one thing on their minds, and that is getting into teenage girls' pants... or anyone's pants actually. They're all hopped up on hormones that are constantly sending brain signals that they need to engage in sexual activity.

They experience this as the need to reproduce is inherently bred into their genes for self-preservation. This is why it's dangerous for teenage girls to go dating. No, it isn't fair, not in the least.

It's okay though. You are young, and you should focus on enjoying your life and all of the experiences that you can. Relationships will come and go in time; best not to dwell on that.

the old saying goes, a father of a son, only has one dick to worry about, but the father of a daughter has to worry about every dick.

I only have girls, so I can't honestly speak on the matter. I do know that the thought of my daughters leaving the nest, is terrifying for me. It's a little ways off in my case, but I know it's just around the corner, and I will need to put on my big boy pants when it happens. I know it's the natural course , and I can't interfere with nature....as much as I would like to keep them under my wing forever, it wouldn't be fair to them.

Your Dad explained it for you. Part his fears that you can't defend yourself, or will gladly go along, or will get pregnant, or his scared of losing you. The boys and girls here were allowed to "group" date until it was felt they were mature enough to date alone. Your time will come.

He should teach his boys how to treat women and focus on that MORE than worry about his daughter dating. There is a lacking of "good men" in this world.

Boys are rough and sweeten up when they begin to date girls

Girls, however, are sweet early and tend to take a turn for the wicked when they begin dating boys

Sounds like your dad is projecting how he did it, on you. In other words, it's hypocrisy.

Instead of teaching their sons to be decent with women..... What a wonderful world.
