It doesn't mean you failed as a father. You did the best you could, and you should keep doing it. There may be no way you can stop her from having sex, but there's no need for you to help her by allowing her boyfriend to sleep over.

Look on the bright side. You have a daughter who feels comfortable enough with you to tell you that. The reality is, you can't keep them sheltered forever, so the better thing you can do is be a cool parent and keep a box of condoms in an easily accessible area. Once in a while, check the box and replace it if it's low. It's better for her to be well informed so she can make intelligent decisions, like not becoming another single teenage mom.

Smacking of her life right there!! Kids suck these days...

Not necessarily. He can't prevent it, but he doesn't have to condone it by allowing sleepovers.

You know, it is very possible that she is saying that just to wind you up. Besides, a teen who wants to have sex, will have sex, no matter what you say or forbid. Better prepare them by having a talk on safe sex and contraception. Just forbidding will only lead to teenage pregnancy and/or STDs. Show your kids you trust their judgement and give them wise guidance. It's the best way to go through that delicate time.

I guess parents aren't doing enough discipline for their children these days.

What a *****. Sorry OP

You can look at this two ways OP. The first way is that she has had sex with four guys, but on the plus side she is honest.

if she starts charging now it'll be a long profitable career!

This is when you call in Madea...
