You might start reflecting on why you asked him about threesomes to begin within.

Why bring up a discussion on a sexual experience you have no interest in? When you asked him, his mind went to, “oh, this is great, I can expect to have a threesome soon”. Then you told him no.

That could be construed as teasing him.

In the future, don’t ask about interests in sexual exploration unless it is something you are curious about.

For clarification, would you be open to a threesome with two men? If so, perhaps you can explain that to him.

Also, this is not “something so little”. You opened a discussion on something very personal and private, and then dismiss it as minor.

Yeah, WHY did you ask him that question, only to shut him down in disgust when he answered you? I think he feels like he was set up, and that no small thing.

I would have stopped talking to you too.

To be honest, we don’t really know how it went down, this conversation.
Maybe OP didn’t tease him with blinking eyes, going like “Hey tiger, wanna threesome?!” Yes?? Pity, nope…, I don’t wanna… ”
Maybe it went something like this:“Well, while we’re on the subject of sex…, threesomes…, would you ever do that?”

But still, I don’t think, from your description, that he reacted angry at all, maybe a bit shaken, or unpleasantly surprised (because he, as opposed to you, does like the idea if it, but was wildly woken from his short lived daydream.

Sounds like you should talk more about expectations and wants (about relationships in general, about sex in particular), and with a bit more understanding of each other’s emotions.

Sexual behavior and sexual appetites are such little things? Maybe they’re not small to him.

It could definitely be construed as teasing. Especially if the couple hasn’t gone all the way.
I try to be respectful, and patient with sex in a relationship (hell the last time I was with a girl, I made her wait,)but men do have needs. The needs can manifest themselves like a type of addiction. When females dangle it in our face, and pull it away all the time, it becomes frustrating. Not cute. Not flirty.

I broke up with at least one girl because she would always get me ready to go, then stop at the last minute. I can’t speak for all men, but such things become a situation almost like the girl’s fucking with my head. I don’t tolerate that. She can take her games elsewhere…

You say you’ve been talking to him for a few months. Have you ever actually met?

Yeah. For how much information there was, there wasn’t a lot of important information…

@janbb we have met yes

Then I suggest you get together and talk it through and own the part that he might feel you were leading him on.
