He uploaded videos to his blog of himself having sex with his girlfriend Vivian Lee, while inviting others to join in.

Common avenues for sex education are parents or caregivers, formal school programs, and public health campaigns.
Traditionally, adolescents in many cultures were not given any information on sexual matters, with the discussion of these issues being considered taboo.
In many African countries, where AIDS is at epidemic levels (see HIV/AIDS in Africa), sex education is seen by most scientists as a vital public health strategy.
Some international organizations such as Planned Parenthood consider that broad sex education programs have global benefits, such as controlling the risk of overpopulation and the advancement of women's rights (see also reproductive rights).
Rubin and Kindendall expressed that sex education is not merely a unit in reproduction and teaching how babies are conceived and born.
It has a far richer scope and goal of helping the youngster incorporate sex most meaningfully into his present and future life, to provide him with some basic understanding of virtually every aspect of sex by the time he reaches full maturity.According to UNFPA, "A 2010 review found that 'gender-focused' curricula – meaning curricula that integrate gender equality into the learning material – were substantially more effective in reducing risky behaviors than programmes that did not consider gender." Research has also shown that delay in sexual initiation, use of condoms and practice contraception has been a result of young people adopting egalitarian attitudes about gender roles.These individuals were also found to be less likely engaged in violent relationships and have a lower rate of STIs including HIV and unintended pregnancy.Adolescents have suggested that sex education should be more positive with less emphasis on anatomy and scare tactics; it should focus on negotiation skills in sexual relationships and communication; and details of sexual health clinics should be advertised in areas that adolescents frequent (for example, school toilets, shopping centres)." The 2007 study found that "No comprehensive program hastened the initiation of sex or increased the frequency of sex, results that many people fear." Further, the report showed "Comprehensive programs worked for both genders, for all major ethnic groups, for sexually inexperienced and experienced teens, in different settings, and in different communities." "It is taught over several years, introducing age-appropriate information consistent with the evolving capacities of young people.It includes scientifically accurate, curriculum-based information about human development, anatomy and pregnancy.Kearney (2008) also defined sex education as "involving a comprehensive course of action by the school, calculated to bring about the socially desirable attitudes, practices and personal conduct on the part of children and adults, that will best protect the individual as a human and the family as a social institution." Thus, sex education may also be described as "sexuality education", which means that it encompasses education about all aspects of sexuality, including information about family planning, reproduction (fertilization, conception and development of the embryo and fetus, through to childbirth), plus information about all aspects of one's sexuality including: body image, sexual orientation, sexual pleasure, values, decision making, communication, dating, relationships, sexually transmitted infections (STIs) and how to avoid them, and birth control methods.
