Age rating for my film

The age rating for this film is a 15, I chose this because it can be a very wide audience who witch it as it will be very thrilling an griping drawing in the younger audience however there will also be a more mature audience. An age 15 rating film is allowed:

• strong violence
• frequent strong language (e.g. 'f***').
•  portrayals of sexual activity
•  strong verbal references to sex
• sexual nudity
• brief scenes of sexual violence or verbal references to sexual violence 
• discriminatory language or behaviour
• drug taking

Although in the first 2 minutes of my film there is none of these thing it allows the rest of my film to involve some and seeing as a stereotype for teenagers is strong language, strong verbal references to sex and many others.
At 15 sexual activity can be portrayed, but usually without strong detail. Some sex scenes can be quite long at this category.
Though nudity may be allowed in a sexual context there will usually be no strong detail. There are no constraints on nudity in a non-sexual or educational context. There can be strong references to sex and sexual behaviour, but especially strong or crude references are unlikely to be acceptable unless justified by context. Sex and sex references are treated the same irrespective of sexuality
