I was a bottom for two years with the first guy , I was too young and too tight to enjoy it at first but got to like feeling full and the movement inside me was amazing. I love being fucked or having things put inside.

I've bottomed for more than one guy in a night twice. The first time, the first guy was quite large but just wanted to ram it in and fuck me hard. He wouldn't slow down and let me get used to his size, so I said we're done. The next guy that night was average size, but awesome. Fucked me in a few different positions and was a lot of fun. Second time, the first guy was large, but took his time and I really enjoyed having him in me. After he came, I found another guy, but he was the same as the first guy I talked about, just interested in ramming it in, so I said nope, we're done. Generally, I find average sized guys are better; they don't assume you're going to love it just because of their size.

I’ve had 3way fantasies, but no actual experience yet. Of the six guys that fucked me over the years, one of them lasted longer and it felt wonderful. The longer he went, the more I wanted it.
I understand your desire

I had one guy last for a while, but I still wanted more. He felt so good.
The others were okay, but none lasted long enough.

I've been bred by 6 or 7 different guys over the years.
The best was in 2015. Nice size and shape of penis, and the right position to receive it. I was dribbling lots of precum, but hadn't come before he did.
I'd enjoy that experience again, but a longer session (honestly, the longer we went, the more I wanted it)
