Much like my sexuality, being a switch hitter, I enjoy both sub and dom with both men and women. With my wife I'm usually the dominant one but now and then she'll take over and do things like smother me with her pussy and say something like 'you might have swallow more cum but this pussy has satisfied more men than you ever did'. Usually when she's not thrilled with me. With men I do what they like to get them to cum. If a guy wants to be in charge and skull fuck me making me gasp for air, okay, because when he cums I'll be there to gobble it down. If a guy wants me to fuck him silly to make him cum, okay, I'm there, pulling out and going down to swallow him up when he's done cumming. It's just as good for me to do the cum clean up as it is to get it straight from his dick. When it's my choice, I prefer to be bottom for both men and women. With women I like them to ride me cowgirl style. I love tits pointing down and rubbing my chest. With men I like to be more effeminate and have them use me as a cum dump.
I think most of us here are dominate with women and submissive with men, at least us that are bottoms. I like the man to take control as long as he's not abusive. When I'm with another man or a group of men my feminine side takes over my sexuality as I am wanting to provide nothing but sexual pleasure in any way I able to do so.
I have to be the dom one when Im giving it to her, but I am always happy to take the sub role when the strapon comes out.
This topic always interests me because (1) I'm neither dom or sub in that sense and (2) my mind doesn't work like that. I'm... consistent with both men and women and I... adjust or adapt to the given situation. Yes, when having sex, I consent and submit to it, whether it's with a woman or with a guy. I don't see myself as a submissive even though it's believed that cocksucking is a submissive act and, more than likely, because of the way women were thought of way, way, way, way back in the day. Yes, I consent and submit to a guy fucking me but I'm not thinking of him as being dominant and I'm sure as hell not being submissive - I'm being screwed because I want to be screwed or I'm sucking his cock because I want to do that and not because I'm submissive. I know that when I have sex with guys, I can "be the girl" and I'm okay with that... but I'm not submissive or dominant. I've been in bed with dominant women - which is fun - but that doesn't make me submissive unless you want to consider that I'm allowing her to be the way she needs to be in bed. Adjustable and adaptable but neither dom or sub. I used to have a very gay boyfriend who, depending on what was going on, was either very damned submissive or dominant, i.e., he'd often literally tackle me to the floor so he could suck my dick - but if we were in bed, he was so submissive that it used to annoy me because I didn't understand it...
I'm almost always fem/submissive with a guy. I can be dom or submissive with my wife depending on her mood and how turned on she is.
As I explored more of my bi side, the more submissive I became. It was new to me and I was more into the moment the more I was told what to do. Nothing along the traditional Dom/Sub dynamic, but letting him be in control of our time together. The first time I spent an hour with a man who asked me to take on that roll was absolutely amazing!
The friend I play with is super sub, like wants to be ordered and told what to do. Forced to his knees and face-fucked. He asks me to gag him with my cock. I enjoy the power, but I'm not really a dom either. I'm more a mutual pleasure kind of guy, but not a dom. It's an interesting dynamic. I will face fuck him and make him gag, but when I'm ready to cum, I prefer he slow down and just suck me to completion. The feel of his tongue just under the head of my dick sends me over the edge every time. He swallows every drop, of course and he gives a better blowjob than any woman I've ever been with. He will always be my sub.
When in BDSM mode (or, more accurately for me, Dom/sub mode) I'm Dom only. With women, men,TGirls, it's Dom and Dom alone. I believe a good Dom will have tried being a sub, but I think I was the world's crappiest sub.
I'm a sub bottom with guys. My goal is to have him experience what he can't otherwise. I prefer he takes charge in using me to achieve his needs. And, the more he enjoys the process, the more I get off on it as well.
