Search Results: flirting with everyone at school

So, I've always known I'm bisexual, but something is telling me that perhaps my observations may not be accurate.
In my lifetime I have only dated one person and it is a person that I am still currently dating today. It is a man, and I am devoted to him and we do plan to marry in the future, but don't let that stop your conclusions right there.
You know how typically, in the man and woman relationship, the man tends to look at other women and check them out even when they are still in a relationship, but the woman doesn't? Well this case is different for me, and I feel terrible because of it.
The man I'm with now, and the only person I've ever dated in my lifetime, is the only man or person for that matter that I've ever loved and I truly do love him. We do plan to marry in the future, and I am pretty sure that he is my soulmate as we do connect on numerous different levels.
However, I've had other people on my mind and when I walk the hallways of my school, and I pass by hundreds of people a day, I can't help but notice and steal a glance at some women do I tend to think are attractive.
I've seen and have many witnesses that my boyfriend as a matter of fact does not check other people out, and he's completely devoted to me as much as I am to him, but I feel as if I'm not as devoted as I may say that I am. I am not in love or have had a crush on any man except him. Everyone else was female.
Is it wrong that I am attracted to other woman in my relationship? Of course I've never flirted with any of them, and would never cheat, because I am in love with my boyfriend and future husband, why do I get a sense I'm more homosexual than heterosexual?

Can a lesbian only fall in love with one man?

(first thing first, i do like him)
I've known him since last year but we weren't very close, at least we didn't have conversations outside of classes.
We have a class together this semester and we chatted on fb a lot. initially he just initiated the chats with like "how's your assignment going" or "are you going to the class tmr?" or "what courses are you going to take next year". Although all the conversations started with a "business matter", we ended up chatting for a few hours about things irrelevant to school works every time.

But then when there isn't a business matter as we've handed in the assignment, he started to initiate the chats with things like "hey haven't seen you online for a while" .(I do initiate chats a little fewer than half of the time, too)

he seems remembers every little thing that I've ever mentioned before, but i don't know if it's because he paid attention to me or it's just that he has a great memory and does that to everyone.

he clearly doesn't show any sign of flirting, just being really nice and we have pleasant on-going conversations as we found out that we have so so many things in common.

but when i see him in college, he becomes a little shy.

not sure if he likes me and knows it himself but is just too shy to show it, or only thinks me as a female friend whom he shares a lot of things in common...

(well im usually the one who ends the conversations because i go to bed early... if this gives more evidence to anything...)
