Secondly, the probability of AIDS transmission is also related to different sexual life styles and physiological structures. Because the anus is not a sexual organ, it is easy for men and women (anal sex) to have sexual life damage, and the transmission probability is the highest, while the probability of AIDS transmission between men and women is relatively lower than that of men (anal sex).
In addition, the probability of spreading AIDS by swallowing semen without condom oral sex is lower than that by spitting it out, because oral sex will lead to the damage of oral gums, and the swallowed semen will not touch the wounds of oral gums, while gastric juice can kill HIV. If you spit it out, the HIV in semen will come into contact with the wounds of the mouth and gums, and the probability of contracting AIDS will increase.
However, I want to remind you that there are many people infected with AIDS, so as long as they have unprotected sex, they are very likely to be infected. Don't try your luck by calculating your own probability. It is safest to go to a medical institution for testing. In addition, I tell you that AIDS has a window period of three months, and the test result is whether it was infected three months ago. If you have had unsafe sex in the first three months, your test results will be inaccurate.
