Can no longer get off alone?

100% TMI warning!

So I've always been big on masturbation. For a few years now I've done it frequently and pleasantly. Then at New Year's I had an intimate encounter with a boy and it was great, and now I can no longer get off on my own. Has this happened to anyone else?

Extra details that might be useful:

- I had only met him a couple hours prior but it was 500% consensual and, like I said above, surprisingly good

- I had never gotten beyond kissing with anyone before

- I'm mostly gay, actually. He's the only boy I'm currently physically attracted to (including celebs), and very much so

- We're pretty good friends now, and I'm also totally falling for him

Thanks in advance and sorry for TMI ❤
