when your are recieving some sort of sexual stimulation from a girl, right before you cum, you take the tip of your penis and place it right at her nostril.

Solarpunk is a movement focused on a positive, ecological vision for a future where technology is used for human-centric and ecocentric purposes. It is a literary, artistic and aesthetic sub-genre and is also closely tied to eco-political activism. Solarpunk narratives have a distinctly positive and utopian foundation in contrast to the often dystopian visions found within other "punk" science fiction genres.

while having sex, just before the climax of ejaculation stick your "head" in or just around the nostril of the girl and jizz in it, until it oozes out like a runny nose.

Chlamydia.
When your penis is runny.
