I always get mixed signals from bottoms how they want to fuck. Believe it or not as a top I want to give pleasure to the bottom too. I get the impression a lot just want to please me but I refuse to believe you guys dont give a shit about YOU getting some pleasure. I love to fuck the guy until he cums and the bottom has lost total control but seems more difficult for some. How to make you happy, what do you guys really want? were do you want me to cum etc.
It's really great that you're the kind of top who wants to please your man. Here are my thoughts.
How do I want it? I like him to start slow, make me feel that entry and give me a chance to adjust to his size, feel the stretching and filling. Then fuck me hard and deep, and mix it up - work the angles. If we're in a body contact position, I like him push deep and hold it there for a moment, body against mine and I feel him inside and out, before he gets back to fucking me roughly. Missionary, or doggy is great for this. Lean over and make body contact and hold me, then let your lust take over and get fucking me again. I like to feel strong hands gripping me, guiding, controlling me.
I don't mind if I don't cum. I want him to enjoy my body. The enjoyment for me is the feeling in my ass, and the psychological satisfaction of submitting my body to another man. It is nice to cum from prostate stimulation, or him jerking me off, but it takes some effort and I only want him to do that if it doesn't distract him from his enjoyment.
I know how I want it, and every guy is different. It might seem obvious to say that the bottom should tell you what he wants, but it's not that straightforward. Many of us feel that it's an imbalanced power dynamic (which is fine, it's what we consent to). I think many bottoms feel that they should not be making demands or requests of the top, especially in a casual hookup situation or if they're not well known to each other. Bottoms should be clear on where you can cum and safe sex choices, but beyond that, many may feel that they're the submissive, they do what they're told.
You can help by asking the bottom how he wants it. Or put it as "what can we do together" that you'd really like? Put him at ease, give him time to open up, maybe in a neutral situation before the clothes come off. If you've been fucking this guy with a really tight body and you make him cum, that's great! You've established a rapport. Ask him what else you can do together to help him enjoy more.
