Straight but feel very horny in my ass.

I’m straight but I feel very horny in my ass. Like I need a dick in my ass. I need to be stretched out and filled. I’ve dildo’d my ass before and came without touching my cock which was limp the whole time. Idk what to do. Sometimes I also get the desire to suck dick. I’ll see a guy at the gym and get the urge to let him throat fuck me.
