It shouldn’t. If a girl’s body isn’t physically ready for sex (she hasn’t produced enough natural lubricant) then sex may be a little painful. This can be avoided - mainly through communication between partners. However, there are certain medical conditions that can make sexual penetration painful and uncomfortable for the female and she will need to see her doctor about this.

If it’s a first date or a first kiss and you are still getting to know the other person maybe take things slowly and not use tongue on the first kiss.  When you are more comfortable, you might start using some tongue but you don’t have to use it all the time.  There is no rule book on kissing but paying attention to how the other person responds may help you (e.g. do they pull away and say, “Yuk!  Brush your stinking teeth!”)

Biologically, sex is about reproduction and puberty is the body making it ready to reproduce. It is also illegal in Queensland to have vaginal sex under the age of 16 and anal sex under the age of 18. Emotionally, young people who have not yet reached puberty are unable to fully realise and recognise the implications and consequences of being sexually active.

Withdrawal is an ineffective method of contraception for younger people. Younger men tend to ejaculate much more quickly; sex with partners is newer to them so it's tougher for young men to anticipate when their orgasm is going to happen or has even started happening; younger people are often just learning how to communicate with each other well about and during sex; and young people are also often more fertile than their older counterparts. These are some reasons why even advocates for withdrawal overall will express that it is not often the best choice for young people.

It also gives zero protection against STI’s!
