<human>: Can you provide a brief overview of the text?

So every summer, my highschool friends and i go on a month long road trip. This year we decided to go to chicago ( we're from toronto) and see what all the hype is about. 

We got there and decided to go to a local hniversity pub for our frist night out. Before this- we drank lots and all of us were very high. So when we got there, like the boys we are- we ended up chatting a bunch of girls. During our night we made it clear that i was in a commited relationship ( fake call/text from girlfriend, made fun of me for not being allowed to hook up ect) so that none of them would get any mixed signals from me. 

The night went smooth and we decided to dance with the girls for a while, all my of my friends successfully were hooking up with said girls so i just decided to have some fun myself and just dance amungst the crowd. Somehow, i ended up in the backside of club and i felt a tugging on my arm- i thought someone had fallen and needed help up so i resisted and remained dancing until what seemed like another arm pushed me. At this point, from what i remember i was being forcefully pinned against a wall and i was kissed by one and necked by the other. As soon as i collected what was happening i pushed them both off and walked toward the bar rails and hung out there till everyone was ready to go. 

Its been a few days and i dont know what i should do. Should i tell my gurlfriend what happened? This'll crush her but i dont want to hide this as itll feel like im cheating and holding something against her.
<bot>: went out of town for a boys trip. Went to alocal university bar- got kissed and necked by two girls- dont know whether totell girlfriend or keep it a secret
