I may identify as demisexual. I havent had a relationship, but i may only be comfortable with someone i have a close emotional bond. The closest pleasurable sex has been with someone i not only close to but emotionally involved with and had reciprocated feelings. My "best" sex was my first time with my best friend who was gay and curious about women. What made it great was we were best friends and loved and trusted each other and we spent the entire time laughing so no pressure, and both of us were new to sex so we were on the same level.
