<human>: After an event my girlfriend and some friends came back to my house after a long night of partying. Upon entering the living room I see my girlfriend's recently acquired (rather attractive) "gay best friend" spooning my girlfriend on the couch. I am not an insecure person, nor do I think that this guy is going to make a romantic move on her as he is quite clearly homosexual, but seeing them together like that gave me a very bad feeling.

The next day I confronted my girlfriend about this saying "how would you feel if I came over to your house with an attractive lesbian friend and you had to watch us spoon in front of you?" She immediately got defensive claiming that she wouldn't care since there wouldn't be any sexual tension and making me feel like I was crazy and paranoid for being bothered by it. Knowing my girlfriend as well as I do, I find it very difficult to believe that she wouldn't care and how defensive she got made me even more... skeptical.

To be clear, I am not really worried about sexual intamacy, but more or less why she chose to be physically intimate with him in my own house. I know her so well that I can see the way she talks and interacts with me is the same way she looks at him and quite frankly I'm getting the whole "oh he's gay, therefore anything that happens, sexually, physically, or emotionally intimately doesn't count," and this makes me worry about their growing level of intimacy.

Condense the text into a few key points
<bot>: My girlfriend cuddled her homosexual friend in front of me in my own house and then got defensive and weird when I asked her how she would feel if the scenario was reversed leaving me with an uneasy intuitive gut feeling that something is wrong.
