Confused about my sexuality

I’ve always felt like I wasn’t straight since I was a kid but never thought of myself as being gay or bi even if I found some men attractive. But in the last few months I’ve lost all attraction to women and started finding men more and more attracted to guys. But I don’t know if I’m gay, bi or straight and just curious for a few reasons.

2. When I imagine my future partner I only see myself with other guys. I just can’t picture myself with women at all

3. When I watch adult content I prefer to look at gay vids but I still sometimes watch straight vids even tho I’m not attracted to the girl at all really. But for some reason I get off faster watching straight vids than gay ones, but I enjoy watching gay stuff more as it feels more intimate

Sorry if this was long or poorly written I just had a lot on my mind and want advice from someone who may know what it feels like, Thanks!
