I don't know if I'm straight, lesbian, or asexual??

I have been freaking out over this for a couple months now. I have absolutely no one to tell this to. This was a big risk putting my problem on the internet. I'm 14 and I get turned on by watching lesbian porn and gifs or pictures on tumblr. The reason why I started looking this up was because when I was 10 I had a friend who was a girl and she told me about bisexuality when I didn't know and so she said that she was bisexual. And we did some things at the time where I was too immature to know and now I feel grossed out about it. I think I blame that for being the root of my sexual attraction to the lesbian porn and stuff. But anyways I have other problems. Ever since I got more into watching porn but mostly gifs and pictures, I've felt less attracted to males and their bodies and pe*is. I know I'm too young to be experiencing this but I need help. I've been obsessing and obsessing over and over again and it's driving me crazy. I have reoccurring thoughts about suicide on whether I'm asexual or lesbian and I just don't want to be either. I seriously have no problem with lesbians , I just don't want to be one because my one side of the family is religious and go to church every Sunday and c**p and then my other side of the family I feel like they'll look at me differently and nothing will ever be the same and I don't even have friends. I'm homeschooled. I barely have three, I feel like I'll lose two of them and nobody else will want to be my friend. When I do think of suicide, I really really want to do it because I have a lot of other insecurities and break down and cry a lot. But I can't make myself do it because I'll hurt this one person who I really care about and I'll go to hell. I just want to be normal. I feel like a no life. But that's not the point. Also, there's this guy who I've been talking to for about 4 months. This was a little before I started getting into the porn, I felt really attracted to him, I have been until about maybe a month ago? I'm a virgin by the way. I'm not ready for sex but when I am I want to know if I want it. He says he loves me, even though we're really young, and he's really sexual. He barely turned 16 in October. He also says that he wants us to get married, and have kids, and live together in the future. I don't really mind. I feel naive for believing him but I feel he really loves me and that I love him too. But he trusts me, and i don't want to let him down. I don't want to hurt him by saying i don't feel attracted to him? He also said he'd love me even if we never talked about or did anything sexual again. I don't know what love feels like but I think that's it. Also, most of the time I don't feel attracted to neither both genders so that's why I'm questioning whether I'm asexual or not. I like the actions that the girls are doing to each other in the Gifs and porn but I wouldn't do that to them, like act on it. Right after I watch the stuff I feel repulsed by males but that feeling fades away after awhile. I'm sorry this is a lot. I'm just really confused and have no one tell this to. If you have read this by now, thank you. I just need advice.
