I'm starting to question my fiance's sexuality. Do you guys think he's Gay?

Well I've been with my fiance for approximately 6 years. We had a child prior to our engagement. Lately I've noticed a lot of strange things going on. I told him I was testing myself for HIV again and I said if anything comes up, it's your fault since your the only man I've slept with. He started getting upset and saying that it was a result of sleeping with other men because he has been faithful. He keeps putting his boxers down and shaking his butt. I asked him what the hell is wrong with him and he blatantly says "What?' as if nothing was wrong with that. He also failed to tell me that he was molested and raped until last month. I don't understand why he took so long to confess this. He said that he was ashame of what had happened to him but I just find it ridiculous especially after 5 years! That's not a secret you would withhold from your partner whom you supposedly love! I don't trust him anymore and I'm no longer going to engage in sexual behaviors with him. I gave him a chance to be truthful and I'm afraid there's more to the story. He had this Asian guy who was super attracted to him in the past but he said that the guy was gay but he never paid attention to him. What do you guys think? Gay or not Gay?
