Lately I started noticing something that I find strange. I am only ever really completely turned on when it's two guys going at it. I think it's so sexy. I then image what it would be like to "take" a man. I think it would feel so fantastic, and want to try it at least once. I'm totally fine with being gay. But there's only one other problem. I'm a girl, and I enjoy being a girl. I only want to be a man during sex sometimes.
I'm not sure if this is just me over glorifying it, or a cause of me being a Sadist. I think that you can't ever dominate someone when you're dependent on them pleasing you during sex.
I know I don't want a sex change because I like being with a guy like that. And I know I'm not lesbian because I hate a majority of women. But a strap on won't work either because I want to FEEL it. I know this isn't normal, but does anyone have any ideas?
maybe you could just get off on seeing the strap on destroy your man
You say a strap on won't work - have you tried one? You may think it wont work, but all you may need is the look of pain in your partner's face (even ask them to act if you wish). And really, to get out your fantasy, you'll need a very willing and very trusting partner.
Methods aside, I do think that you need to see a specialist to talk about your sexuality. This is how serial killers start - the need to "feel" the domination and then completing it with a knife or other method. If you don't get help or methods to excert your feelings, you might completely ruin your sex life and it may cause you to look for domination in other aspects of your life (indeed, it may be a power inbalance in your life which may be causing you to feel the need to dominate). You say you believe that sexual partners can't dominate, so you're never going to really get that feeling of domination while you hold this mindset - you may to abandon it altogether (it's perfectly acceptable for one partner to receive and the other to give).
Whatever the case, you are not gay. You are a girl with some serious sexual issues who needs to find an outlet before it gets complicated.
