Masturbation Techniques

I just watched porn and looked at hentai for 1.5 hours while rubbing my nipples and "flexing" my dick without touching it. Also, I've been doing nofap for like 6 days now. Together it actually feels like I fapped and jizzed even though I didn't. Has anyone else tried this?
More techniques: rub the crown of your dickhead with your forearm, aim for long strokes not fast ones, it gets your dick super sensitive.
What are some other novel ways you can fap?
