When I was in high school, like most guys I was horny all the time. Who ever was up to fucking, boys or girls, I'd woo an screw, ask to join me in mutual masturbation, I just needed to be getting off all the time, I never gave the sex of my partner any consideration. I gave my ejaculations and orgasms consideration and attention.
In college and in my early twenties I had learned much more about the nature of sexuality (mine and others) and felt pleased my attraction to both sexes offered me many more opportunities for sexual experience than those with stricter tastes had. However, I suffered from a good case of the grass is always greener. I loved (physically and emotionally) both men and women. On a date with a beautiful young woman, I'd long to suck a dude's dick. I'd be in bed with a beautiful young man and want to be eating and fucking pussy. It would nearly make me crazy. I guess it was my way of being in denial.
At twenty three I moved to San Francisco and a new world opened to me. I met married friends who invited me into their bed, I met women who enjoyed having sex with me and then enjoyed watching me such a buddie's cock, I found guys who wanted to watch me fuck a lady and then fuck them. I was able to accept Beautiful romances with both sexes and orgies such I hadn't dare dream could happen would fill my live and at this time I began to truly understand my own sexuality (and begin to understand others).
I do have taboos against sex with children, animals and anyone who is in a position to not be able to reject me for any reason what so ever. My type? Someone who has a high sexual aura. I am still constantly surprised at who I find sexually alluring. I honestly believe the imagination leads the cock and balls and if you follow your imagination, freedom will follow.
I do not hide the fact I am bisexual in the least. (Luckily I have always worked in the arts, and NOT on government sponsored art projects, so my co-workers are nearly always accepting and open minded. I am aware if I were buried in middle class suburbs or middle America I could not live the easy live style I have found for myself in San Francisco, Marin County California, Los Angeles and now New York. I am lucky I work in a field that allows me to live in such places.
I have mated (with another man). He was married when we had our first sexual encounter. (He divorced, he had fathered no children.) Our relationship is more than a decade old. We are not monogomous but respect and enjoy each others high sex drive. We both frequently have sex with both women and men, but always return to our bed in order to wake up there in the morning. It works for us, that's all the matters to either one of us.
Today I follow my libido and my imagination. I have no statistics to fulfill, no precepts to live, no mandates to adhere to. My sex life can be and is dedicated to my sexual pleasure, not proving anything but confirming who and what I am. I enjoy being me a great deal.
