This is NOT the moderator talking.
MtlNewbie, I'm thinking about the "ejaculation period", you're correct.
At that point, if there's a hole in the condom, no matter where the hole is, the girl is very likely to get a leak inside her and that leak will be bigger than what the guy might be exposed to with fluids leaking in the condom from the girl.
During normal intercourse, if there is a hole in the side of the condom, away from the tip, the risk to the guy isn't that high because the tip of the penis is covered. For contamination, the viruses need access to an area of thin, moist skin. (for most dangerous STI, not talking about skin infections.)
Of course, it's assuming the condom doesn't completely break and the hole doesn't get bigger.
The condom might break, of course. This will make the risk equally dangerous for both.
