semen contacted cut in nose

[lfx]

dear doctors:

thanks for watching my questions.

i'm gay man.
my hand contacted another guy's semen after his ejaculation, and then about 10s later i used my finger to blow my nose. when i realized on the finger there's his semen, it was too late! and unfortunately i found my nasal mucosa broken when i was blowing my nose ---- i could see bloodshot on the finger!
i also sucked his testicles (only testicles, no more else) and in my mouth there was a gum.

so my question is :
my wound in the nose contacted his semen on my finger. the semen was fresh. and i sucked his balls.
am i in a risk? do i need a test??

thanks for your help!!

THANK YOU VERY MUCH TEAK!!
that means the hiv in semen has already died once it contacts the air?
my LAST question is:
so the semen 10s after his ejaculation can not maintain infectiousness even if it contacted the wound in my nose?

No you were not at risk and no you do not need testing.

HIV is unable to reproduce outside its living host (unlike many bacteria or fungi, which may do so under suitable conditions), except under laboratory conditions; therefore, it does not spread or maintain infectiousness outside its host.

HIV is transmitted by;
Unprotected penetrative anal and/or vaginal sex
Sharing works with other IV drug users
