Boy problems.

I was out clubbing with this boy I know. We went for a walk afterwards and started kissing. We were just kissing and he was starting to finger me before I stopped him. His finger never entered my lady parts. We then walked home. Later I find out that his friend had given him a condom in case he needed it. I’m offended that his friends and himself thought I was going to have sex with him. I’m a virgin in literally every sense of the world except from kissing. I don’t understand how they thought I was going to be easy and have sex in an ally? Sorry if this is immature and irrelevant but this is on my nerves. I thought this guy was nice.
