I need some help on this one badd!!!!!!!!!!!

So me and my best friend, are dating best friends. Now we all went out one night, and we were at an amusement park, and we were all sitting in the actual park area with all the trees. It was dark and about 10:30. Well the 2 girls say
we have a surprise for you!" So they start making out or whatever, and of course, this would turn most guys on....but, bothered the hell out of me, and pissed me off...is this normal? Or is something really hella wrong with me?

its normal in actual fact she cheated on you right in front of you, and you should be bothered it was inappropriate she obviously thought it would turn you on but maybe you should have a quiet word with her and see if you can sort things out....

It was wrong of her to assume you would want her to do that. Try talking to her about it, she should understand.
