it is alright.
I think you need to ask the question, Why is he with me if he is not attracted to me, and also, ask yourself, Why do I want to be with someone who does not find me attractive?
It's just a dream, if you want to know whether you're attracted to someone in your class then ask yourself.
If the person you are interested in isn't going with someone or married then ask them out. It means you are physically attracted to them and that's how it all starts to form a relationship (hopefully.) Ask this person out.
It's perfectly okay to ask.
If you are attracted to them as well and would want to date them, why not just ask them out? If you are a friend/co-worker who is not interested in them, be friendly but ignore any flirtatious comments. If they ever ask you out, just say you're already seeing someone else.
if you have to ask someone else, then in your case, probably no
It is a scary thought that someone would ask this question.
Yes, it is generally acceptable to ask questions about a lecture after class.
It's OK. If the guy likes you he will be happy that you asked him, and if he doesn't like you he will just say no to your offer - and even then, he will probably feel at least somewhat happy that he is thought to be attractive, even by someone to whom he is not himself attracted.
If your girlfriend is attracted either romantically or sexually to other women, she might be gay. You won't know unless you ask, but do it in a way that is not demeaning or threatening. Ask her if she's ever thought about it.
I don't know any reason why not. If I thought someone might not be 18, I might ask for ID.
In this day it is acceptable now for a girl to ask a guy out - so if you have someone you are talking with and/or interested in simply ask them if they would like to get together sometime or go out for lunch, a movie etc.
