The key point here is that you both probably have oral HSV1. For males, this means he is extremely unlikely to obtain a genital HSV1 infection owing to the immunity he has. It may even be impossible.
Your immune system also keeps you extremely safe from a genital infection.
Interchangeable meaning hsv1 can still be on your genitals. that's why I was worried.
No they are not interchangeable. HSV1 is HSV1 regardless of whether it is oral or genital.
but they could be interchangeable. that's why I was concerned
Cold sores are associated with hsv1 you couldn't of given him hsv2
