It's probably only wrong for the guy that you 'love'. We all have little crushes and desires, but if yours is leaning towards the 'going after her' route, than it must not be love that you have for him.
You're experimenting, there is nothing wrong with that. The issue is your desire to date both people at the same time. If you wanted to date 2 people of the same sex, people would tell you, it's okay as long as everyone knows you want to have an open relationship. It's the same thing in your situation. You need to be open with both parties. They both need to know that you want to date both and then you can decide who you want to be with, if you choose to go with a monogamous relationship. It's difficult to come out as BiSexual, especially, if you're still in High School. I would suggest finding a local support group for GLBT young adults. It's not wrong though. Who you are, is who you are. The key in Bi relationships is to be honest with all involved.
It's not wrong. But you should go ahead and explore the possibility that you may be happier with a female now before you are older. At least you wont have any regrets later on in life if you explore this now. You don't want to end up married to a man, but desire a female. That would cause all sorts of issues.
It is human to have urges for both genders, but there is a part of you that will want one more than the other. You have to make that decision for yourself. You have to put aside other people's opinions and societal norms and follow what is in your heart. Love never fails....and it doesn't matter who you love.
depends on who you like more... if the guy has more things that you like about him and he fits the needs you want go for him but if the girl does go for her but which ever way you go if you still like the other then talk to them and see if its ok that you double-date... thats what i did untill i realized what i have and felt like in a way i was cheating... just set you goals on what you have in life and figure out which one is going to fullfill them... :)
