<human>: So let me start by giving some background information on us. My girlfriend is 23 and on her last year of university. She doesnt really have a lot of friends at her university, what friends she do have are mostly guys (aside from a few really close girlfriends who are not at her university). We are currently in a semi long distance relationship where I go to see her every other week.

A while back after a long night of staying up completeing assignments and such, her friends (2 guys which I do not know) decided to hang out to watch some movies at one of their place. By this time it was already 1 am, they watched 2 movies in a row, so it was probably around 6am when they were finished. She told me they all passed out on the same bed.

Now I am not normally a possesive person nor do I get jealous easily, but I cant help but feeling a tad unhappy with that scenario.
When I brought my feelings up with her she turned it around on me and accused me of not trusting her, and told me not to tell her what she can or cant do with friends. I don't think she is completely wrong, although it is not a trust issue, more of a boundary issue.

Now I can't help but feel conflicted about how to feel regarding this situation. On the one hand I feel like she is right, and these feelings are quite highschool, I mean we are all adults, whats the problem here. On the other hand I feel like there are some clear boundary issues regarding what you should or should not do with friends of the opposite sex. I, myself, have several very close female friends whome I grew up with, but I have always kept the boundary very clear cut.

Now maybe there is some cultural differences since I come from a traditional asian background where we tend to be more reserved and the boundaries between sexes are more pronounced. While my girlfriend comes from similar background as I do, she is more attuned to the north american culture.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: girlfriend slept on the same bed with two other guys, I'm not sure if I'm completely wrong for feeling like this is a problem
