The human immune system continues to develop after puberty. The age of exposure has an influence upon if the immune system can fend off infections in general, and this is also true in the case of some sexually transmitted diseases. For example, a risk factor for HPV strains causing genital warts is sexual debut at a young age; if this extends to the cancer causing strains, then sexual debut at a young age would potentially also increase risk of persistence of HPV infections that cause the very HPV induced cancers that are being diagnosed in spiking numbers of relatively young people.
