How did you end up swallowing cum for the first time with a guy?

Hi
when I was 13 or 14 tried to suck my dick but wasn’t flexible enough, but I did manage to shoot cum into my mouth and over my face - wasn’t that keen on the taste, so didn’t bother much after that, until I was in my late 30s/early 40s and to my surprise I really developed a taste for it. Now I always swallow my cum and regret not starting sooner!
