No one will or should judge you in here, you are in a bi forum. Your attitude should be respected and accepted by all on here.
Bi, Straight, dont worry about labels. Do or label yourself what you feel comfortable with.
I am definitely 100% the same. I love and enjoy being with women and connecting with them in a relationship.
With men, in particular my male partner. It is strictly and only a physical sexual relationship. I want that, he wants that and we are both happy with our fuckbuddy relationship. It is mutually satisfying and beneficial to both of us. Importantly we both enjoy roles we undertake, he enjoys being a strong aggressive and Dominant Alpha Male Top and I enjoy taking on a very submissive feminine bottom. So sexually speaking, its a win win relationship for both of us.
You mention, you love the no drama. I hear you. When he has the urge to fuck or release a load, he will send me a text with a time, literally thats it lol. 99% of the time, I am up for it, so I will either agree with a yes or suggest an alternative time that day. There is no games, drama or agenda's at play here. we both have physical needs that need to be met and satisfied. Sexually we have great chemistry and enjoy our time together, so naturally we always look forward to every encounter.
For both of us, the best aspect, is that after sex, we go about our lives seperately till the next time we hook up. If anything we find the uncomplicated nature of our FWB relationship, one of the best aspects of our physical relationship. Neither one of us, wants or needs a relationship outside of sex.
With a girl, at least from my experience, having this kind of relationship is almost impossible as inevitably the issue of being in a relationship and or wanting more or feeling used, almost always comes up.
