Where do you get your info from, dude?
"Male latex condoms, when used correctle and consitently, are effective in preventing the sexual transmission of HIV, and the reduce the transmission of other STDs, such as chlamyida, gonrrhea, NGU, bacterial vaginosis, and trichomoniasis, that are also transmitted by muscoal surfaces. Condoms are less effective preventing infections that are caused by skin-to-skin contact such as Sphylis and HPV." (Crooks, Baur "Our Sexuality" 517).

I tend to agree with the authors of a college textbook on the issue of STIs than a dude on cannabis.com
