'But of course, this reliance on herd immunity doesn’t provide optimal benefit for boys who go onto have sex with other men in adulthood.' JCVI said its final decision would be made after further consultations.
Mr Armstrong said that only a gender neutral vaccination programme can control the rise of HPV, and that parents should not be forced to reach into their own pockets to protect their sons.
Anyone exposed to an infected partner can get an STD in the mouth, throat, genitals, or rectum.
'While there are some additional population level health benefits to both males and females by extending the programme to boys, impact and cost-effectiveness modelling indicates that adding boys is highly unlikely to be cost-effective in the UK.' But experts have pointed out a weakness in the JCVI's herd protection argument.
Jonathan Ball, professor of molecular virology at the University of Nottingham, has previously said: 'It all comes down to cost and how much benefit will be gained from vaccinating boys.'As increasing numbers of girls take up the vaccine then risk of heterosexual transmission decreases and the benefit of vaccinating boys diminishes.
A separate survey conducted during 2007-2010 found that 33% of teenage girls and boys aged 15-17 years reported having had oral sex with a partner of the opposite sex.
Many STDs, as well as other infections, can be spread through oral sex.
And while most infections disappear on their own, without even displaying symptoms, some strains can lead to cancer, notably cervical, which in around 90 per cent of cases is caused by HPV.
It is also linked to penile, anal, throat, head and neck cancer, as well as genital warts.
Hollywood actor Michael Douglas, 72, blamed oral sex for giving him throat cancer in 2010.
The HPV vaccination is currently given to girls aged 12 to 13 but not boys.
Only girls are vaccinated on the grounds that men who only have sex with women would logically also be protected from transmission.
