He is not acting out of kindness

Wednesday, when Lea and Carine brought me to their favorite nightclub (yeah, me in a night club...) I met some of their friends. three of their Thai friends, and a boy from Morocco. He's been kind and polite to me the whole evening. Since I am deaf, a night club isn't the best place to socialise. It was more or less impossible for me to have a proper conversation since I was unable to read on lips and my ears had shut down when the elevator's doors had opened. So he made an effort, talked slowly, facing me, and when I couldn't understand what he said, it typed on his phone. We laughed a bit.
Since, he has added me on wechat and invited me to group conversations, to help me book some jobs as a model. He literally booked me for a job with his own agent and when he realised I was short of pictures to send to agents, he said he'd find a photographer so I can take some new one.
From here, sounded like a nice boy, being polite, acting on kindness and with whom I might be friend. We don't seem to share much, but the circumstances.
But (there's always a but) according to Carine and Lea, the boy's not exactly looking for a new friend. From their point of view, he's flirting with me.
To me, he was just being kind! No innuendo, no signs I could notice. I mean, it's just me. There were some pretty girls out there. I don't understand. I just thought he was being friendly to the newly arrived ginger monster.
But apparently, according to the girls, men here, are all looking for the same thing: girls to have fun with to mess with and to put in their bed. And they're urging me to tell him that I'm a lesbian, so he won't lose his time with me and not feel used, since he doesn't even have a chance with me.
How crazy is that?! I mean, I never asked for anything. why do I have to tell him about my personal life so he won't get upset for being friendly? I'm a bit off, here. According to the girls, I can start being a friend to him after warning him of my sexual orientation.
It tires me, just to think about it. I left France to take a new start, and I'm stuck with the same problem. Anyway, I'll have to find a nice way to make him understand that nothing's ever going to happen between us.
I don't know where he got the idea that there might be. Erg...
