Hi.
There is this guy in my class that I'm really interested in. I only see him twice a week. Im shy and never had a boyfriend before. Can you help me, please? Well I know I should go and start a conversation but I donno how to do?
Thank you :)

It would be very helpful if we knew your age at least. You are correct though Ms. shy girl, that starting a conversation with him is what's needed. Not easy for shy people, nor a guarantee of romance or anything happening beyond that. I assume you have a common class twice a week, so something in common at least to introduce yourself. What if he is as shy as you, or worse, just a cute idiot? Got any female friends you are close to, that may know of him?

Let's start with your age and situation first. Details matter, like why you like the dude, and your impressions of him.

Thanks for starting to help me
I'm 19 and he is 25
What I like about him? Well, just like me he is interested in studying. He is really polite. I really dislike the ones who uses curses in their speaking but he isn't. He is always gentle. ( and of course he visuals. ;D. he is tall and my type)
Beside from being shy, I'm an international student in that class, so its actually hard to find a topic to speak in english rather than my language

Is he also an international student, or an only english speaking native? I get being attracted to strangers, and it's a great feeling, but the important thing is getting to know someone. Does this fellow you fancy hang with a certain group and is class the only way you know of him? Do you hang with a certain group socially besides class time. Just trying to find if there is any social overlap that can be explored, besides the class you both attend.

Romance and dating is really challenging for the shy and inexperienced. A lot of FEAR to overcome. Learning HOW to say hi, and just asking someone's name is scary isn't it? Are you both GOOD students? Course work is the topic you share and a start.

He is from another state but he is native english. Well, he is usually always hanging out with a guy same nationality as me. And yes class is only way. I hang out with my group but we and those 2 barely sit together.
Yes we both are good student. But because we are studying different subjects and that our only same class it's hard to start a conversation

Seems you need to learn just the simple HELLO approach to get someone's attention.
