These rules are very strict, and will be found quite objectionable by those who have previously enjoyed unrestricted sex. But to violate these rules, is to risk unusually horrible death. A condom must be used by a man even when he is receiving oral sex. But manual stimulation of another's genitals is NOT safe if one has cuts on one's hands, unless one is wearing a glove. Note that even when one is conscientiously following the recommendations for safe sex, accidents can happen.
Condoms can break.
One may have small cuts or tears in ones skin. It does, however, greatly reduce the chances. It is particularly encouraging to note that, education programs among San Francisco gay males, has significantly reduced the incidence of new cases of AIDS infection among that high risk group. Between practice of safe sex and a significant reduction in the number of casual sexual contacts, the spread of AIDS is being massively slowed in that group. Similar responsible action MUST be taken by straight folks to further slow the spread of AIDS, to give our researchers time to find the means to fight it.
