Pregnancy prevention and sexual health billboards...

Following two very uniform and coordinated HIV care ad campaigns recently (the We've Got Your Back billboards and the When Needed We're Here AHF Pharmacy billboards), AIDS Healthcare Foundation has followed up with a more scattershot spread of billboard ads to mix things up and keep their message about safe and responsible sex fresh in the skies of L.A.

There's cute babies covered in spaghetti, naked bodies writhing together and simple play on words advertisements all trying to catch your eye.

Daily Billboard's favourite has to be the 'Not ready for parenthood?' pregnancy prevention billboard which really grabs your attention with its orange colour and messy child getting into to trouble with some spaghetti. The message kids, use a condom or this could be your unplanned future.

This funny spaghetti baby billboard was spied along Sunset Boulevard on July 29 and also along Highland Avenue on August 8.

Meanwhile the 'Sexual Revolution 2' billboard really draws you in as you try and work out how many bodies, and what parts, and what genders, are involved in the ad creative.

Unlike the sexual liberation movement which started in the 1960's through the 1980's, this new sexual revolution is all about battling for freedom from stigma, proper sexual education, access to condoms and an open sexual dialogue.

Let's face it, it's a pretty captivating ad to encourage people to find out more and was spotted along Sunset Boulevard and Cahuenga Boulevard on July 29.

The 'Hook Up W/Us' creative is a nice nod to the new casual sex generation who use mobile apps to hook up with multiple partners, far easier than it was possible in the past before technology made sex so easy.

This rather simple, but clever copy-only billboard advocating free STD (sexually transmitted disease) check-ups was also snapped along Sunset Boulevard on July 29, 2013.

UPDATED: Here's a second wave billboard for the Sexual Revolution 2 campaign, spied along Highland Avenue in Hollywood on December 22, 2013.

This tangle of hands and bodies comes just in time for the festive party season, when alcohol can often lead to some risky sexual decisions.
