Wearing a condom has double advantage
Using a condom while having sex protects you from becoming infected with sexually transmitted diseases such as HIV. At the same time it also prevents unwanted pregnancy.
Selecting the right condom
There are several types of condoms available in the market that you can choose from
Most condoms are made of either latex or polyurethane. Latex condoms are more effective in terms of providing protection as chances of tear or leak are less. However, latex condoms will easily tear if an oil-based lubricant is used. Some people may also be allergic to latex
Polyurethane condoms are thinner, which may give some users better sensation and pleasure
Some condoms contain a spermicidal chemical called Nonoxynol 9. Till recently it was thought that adding it would provide better protection against pregnancy and the transmission of HIV and other STDs, but recent studies have shown no added advantage. Size of the condom should generally not be a concern as most condoms fit most men. The definition of regular, large, and extra-large is not consistent across brands. It may be a good idea to try a few products to figure out what works the best for you. The basic idea is that it should not be so tight that it pinches or so loose that it slips off.

Thank you very much, Teak
No, it can cause the condom to fail. If it doesn't fail there is no risk of contracting HIV. It doesn't cause the HIV to penetrate the condom.
if using condom + the slippery from oil, can aids virus penetrates the condom?
Not a latex or poly condom.
