I like sucking guys with big cocks because I have a tiny dick and keep thinking how I wish I had one like them it makes me feel so much like a sissy when I do and gets me so turned on and horny

Any cock feels big, when its in your mouth, Kyle.
Especially if it has a big head. What is needed is being long enough to touch the back of your throat. With me, if a guy is thick also with nice balls that is certainly a plus.

I've had big and smaller. Seen little difference in the taste, amount, thickness and runny-ness, and smell, of semen. If he's totally into it, he'll give you that mouthful you crave.
Let me know how you do with your first.
