Because of this, it’s absolutely necessary to use a physical barrier such as a condom in every sexual encounter because the skin of the mouth, vagina, penis and anus is so delicate that it might have some tiny cuts or sores that can act as an open door for HIV infection -or other STD infections.
Dahil dito, kinakailangan talagang gumamit ng pisikal na harang, gaya ng kondom sa bawat pagkikipag-sex, dahil ang balat ng bibig, ari ng babae, ari ng lalaki at bibig ng puwit ay maselan at maaaring mayroong mga maliliit na hiwa o sugat na maaaring magsilbing bukas na pinto kung saan makakapasok ang impeksyong HIV-o iba pang impeksiyong STD.
