Am I Too Territorial?

I was recently talking to someone about threesomes; hey, i may be gay, but I'm also a guy. I said I wouldn't like to have a threesome. When asked why I replied that I wouldn't want someone else to be doing things with my significant other, regardless of gender. I just couldn't have that. It gets worse. I said that I wouldn't want my significant other to make-out with someone else; again, guy or girl. A tap kiss to the same gender is fine: friends do that all the time. My friend said that they wouldn't mind as long as it were two of the same gender, but opposite gender it's different, it's competitive. It's just a kiss means a lot to me. I only kiss those who I am connected to. Oddly enough, I would sooner have sex with a stranger than kiss them. Sex is all about pleasure; a kiss is intimate, a connecting of the souls. Even if I had permission from my significant other to kiss someone else I would feel terrible. I hope I'm not becoming conservative. Someone help me. Am I too territorial? Am I just weird? I don't know. Any insight would be great; please comment me something.
