I’ve had sex with a condom twice. I’ve swallowed for 4 different guys. But I’m positive two of them didn’t have an STD. What are the odds that I do?

can you give me percentage chances of catching a STD especially AIDS with an infected partner?and what are the chances if you do it with a condom?also are some positions or techniques helpful in reducing the chances of catching an infection?

i do not have an std, i know this for sure, i was just curious as to what the chances are?

I had sex with a stripper and i wore a condom but i noticed the condom wouldn’t stay at the base of the penis. It would roll up a bit but not completely off. I did not ejaculate either. How safe am i? do i have an std? Should i get tested?

iff a woman is on birth control is it really worth wearing a condom. What iff people have been using condoms their whole life but want to get pregnant, whats the chances one of them have stds.

Or are stds just a rare problem that mainly comes up with people who often have sex with diffarent people without using condoms?

15 years old and masturbate around three times a day every day.
Can this increase my chances of PE?
Thanks.

I had sex with a person who is not infected with an STD, but i did not use a condom.

What are the chances of having an STD?

What are the chances of a male getting an STD by receiving unprotected oral sex? Assuming he is healthy, no other infections or diseases, no cuts or sores etc. Many sources simply say it is possible to transmit STDs via oral sex so you must use a condom. I am interested in a more detailed profile of the risk involved for a male receiving from a female. Which diseases could be transmitted and what kind of infection rates are shown for them?

Sorry about the repeated details!
I guess I should clarify my question. I have already read the advice “always use protection.. STD transmission is still possible” and I am not asking for that. When I said what are the rates of infection I actually meant:

What is the probability specifically for an individual male that he will become infected by an STD from receiving unprotected oral sex from a female. What the infection transmission chances for any relevant STDs in this specific situation?

I’ve never done it before. I’m pretty sure she doesn’t have any STD’s. But I’d like to know the chances.
