I gotta research it. I feel like I am dumbass because I am a college educated person.
Because natural condoms can have holes (not large enough for semen to pass through, but enough for HIV to slip through), yes, you are at some risk.
However, 95% of the condoms you'll find in a drug or grocery store are latex. The remainder are non-natural alternatives for people with latex allergies- these do protect you against HIV as well as latex condoms.
I would be very, very amazed if someone managed to find a natural condom in a non-specialty retailer.
