I think I’m turning my girlfriends husband into a cuck

So we’re doing some of this. Before her he never even kissed a girl. Up until he caught us I don’t think he even knew what a clit was. So he’s been “researching”. She told him getting information off of the internet isn’t going to help. She said if she wants to learn he should ask me. She told him the reason we started was so she can be more comfortable doing different things and that we had planned to bring him in so he could learn how to do different things. He believed that. When she says he should ask me stuff he just says he’s not ready for that yet. So when he’s all horned up he asks questions of what we did. And the. He asks if she minds if he jerks off. And no. She doesn’t do anything with him unless they are talking about us. But then he goes into another phase like yesterday where he does t want her to have any contact with me at all. And she finds him going through her phone looking for messages between us.
So I even had her text him a message saying I like it when you get turned on when we talk about certain things. His response came from chatGPT. It was something generic bullshit response acknowledging he appreciates that she like the communication and looks forward to talking more. Or some bullshit like that.

I’d be a little weary about telling him he’s not able to satisfy her sexually at this point. He’s still pretty fragile.

Before he found out about us she would comment to him he needed someone to teach him things. He would respond with. I know, im sorry I’m not manly. And then I heard how aroused he got when he saw the videos. When he asks questions about what we did he’s not upset at all. And then he qets aroused. And let me tell you. The videos he saw. He saw one where I’m cumming on her face. He saw my cock as I slid it in her. He saw bondage videos and blowjob videos. He even mentioned to her how much larger I am than him and asked it felt different. But then like I said. He flips the next day and doesn’t want her to have any contact with me.

They’re both 41. Been together since early 20’s. I guess as far as trust, he probably lost that since he found the videos of her with me. She trusts him not to cheat because he’s never been with another woman. But she lost trust in him in a sense because there have been a few times where he’s taken advantage of her sexually when she was drunk. And one time just forced himself upon her. The other trust issue with her is his family treats her like shit and he doesn’t stick up for her to them. But then they also treat him like shit and he just takes it. He doesn’t stick whatever they say. And if I’m being honest, he does whatever she says. I understand the masterbation thing. Tonight I told her to bring up how he was turned on by the videos. If he admits to it again to start Jacking him off and try to get him to be more specific as to what turned him on. He’s still at a point where he doesn’t want her to talk to me. But he seems to be easing up on that today and yesterday. Like he’s not as insistent. So idk how calling me a better lover would go over right now. lol. Is that how you want to be talked to? What would be some signs that he would like that?

So a little bit of an update.
Heading into this weekend my plan was for her to give him a handy or let him take care of himself. I told her to ask him what turned him on the most from the videos. Talk specifically about what he liked and work it for him to admit he got off seeing us together.
Friday night they mostly discussed how he took advantage of her those few times. He completely blames himself for our affair. He said he wishes he never did that and that he’s a bad husband. He’s a bad husband for doing that and not sticking up for her to his family. Finally she asked him what turned him on the most from the videos. He was surprised by the question. She said a lot turned him on. Like her being tied down and he said he likes blow jobs. He asked for a handy but she refused. She said she wasn’t ready to do that to him yet but it was ok if he wanted to take care of himself.
Saturday he took her to a concert and got home late so nothing happened.
So I knew he was expecting something to happen Sunday night. So this time I told her to tell him she likes that watching the videos turned him on. That we talked alot about bringing him in so I could teach him. And him watching was kind of like he was there. That she would like it if he watched. I also told her if she gave him a handy to twist her hand so it was different than she ever did to him before. So Sunday night arrives and they get into bed. She reaches over to give him a handjob. She starts twisting her hand like I told her to. He comments. Wow. This is new! Is this something he taught you? She said. Yes. He immediately came and said “blastoff”. Wtf??!! She told him to never say that again. I asked if he’s normally a minute man. She said yes. I asked if she thought he came so quick because she told him I taught her that or because she was touching his dick. She said she thinks it’s both. Any thoughts?

Interesting take. Thanks for your advice.
