Since you two are compulsively linked now, on a psychic level, it’s natural you’ll continue to experience each other’s feelings and emotions this way. It doesn’t sound intentional to me, the way you describe.
He will be picking up on whenever you feel sexual (e.g. when you’re RSing), or when your defences are down (between wake and sleep) and start responding to you emotionally. He might even be addicted to the feelings, and so keep attaching to them. He might sometimes be masturbating when you are ..that’s when it feels particularly intense.
It’s hardly surprising; if you created a ‘soul’ connection you don’t just close it down in an instant. It’ll take time.
You need to gain control of it; that means practising emotional detachment from the feelings. Tell yourself they’re just good feelings. Fine. No need to tell yourself any stories/narratives around those feelings. Detachment.
If you give it no attention, or focus, it’ll eventually disperse: you might even be able to infuse those sexual feelings into another relationship ...fantasize about the one you WANT to fantasize about, and it should eventually come true ...another ‘soul’ connection*
(after all, you need to set him free from it too... especially your responsibility if he’s unaware of this stuff!)
Good luck :-)
*having said this, we have strong preferences for people who emit certain energy signatures/frequencies (though of course those vary according to their emotions, their feelings towards you, etc.) So, meaning, there isn’t only one ‘twin flame’ for you out there... it may be a question of finding a ‘feel’ you like as much as you liked his, only that belongs to someone more outwardly suitable.
