I can't look at my mom the same

I'm scared I (18M) might be sexually attracted to my mom (45F).

A long time ago, my mom was always against me seeing her naked. But the day i turned 18, stuff changed. She became much more open to the idea of me being around her, allowed me to come into the bathroom while she took the shower or when she was doing other things. And now, its pretty much normal for her.

My mom is tall, around 5'11/180cm with me being 6'1 or 6'2? I have no idea, i'm not american. She's blonde with a massive chest and a fat ass- God it's weird describing her this way even. Thick thighs, nice still somehow non-wrinkled face. Her belly is like, cutely "fatty". Y'know what i mean.

Lately, as mom became more open to seeing me naked and me seeing her naked, it became weird for me. I was coming back to my room with a boner so hard you could smash rocks on it.

I have no idea what to do. My mom is simply hot. I'd fuck her 100%, but i'm so scared!

What Should i do guys?!

I'll keep y'all updated!
