Does it seem like he’s unsure about what he is or because he’s Swedish thats why he said this? His english is pretty good ?

In a long distance relationship, the guy is 30 this is his first relationship with me he’s never had a girlfriend before but few hookups. I’ve asked many times if he’s Bisexual & he’s always said he knows what he wants & NO! When we first met I sent him a meme in that meme had a football he knew and said he’s pretty handsome he can find guys handsome, I know when he was like 12 or 15 he watch a gay porno and due to that I’ve probably asked more then 20 times if he’s bi and he always tells me he is not. One day I mentioned when we first met and was just friends he asked if I was bi I said no then when I ask him he said something like he’s pretty sure he’s not or so far he’s good and I ask why did he say that and he said he doesn’t really remember he can find men handsome say their handsome but he doesn’t think he’s bisexual but in 10-15 years who knows he said even I won’t know about my sexuality. I kinda flipped on him then he said I’m taking it the wrong way he’s talking about other people but with him I don’t have to worry he knows he’s not bi but I was still upset then told him I experimented with a girl when I was 16 and I know I can say for sure I’m not bisexual and I ask him if him knowing now that I did sexual stuff with a girl turn him on or off he said neither it’s in the past and when I asked a trick question if he would want a threesome with me and another girl he said seeing another girl touch me is like another man touching me he said I can leave if I want that
