Saying you're gay first and bisexual second, sounds to me like someone saying, "I'm a vegetarian, but I sometimes eat meat." Ummm, wait, what???
So, please don't be offended if a lot of people are confused. They'll also probably read what you said to me, "I love my wife, but in a non sexual way." So you probably will NEVER get any other female interest. Which may be what you want. But, again, don't be offended if a woman ever rejects you. She's probably just wholly confused
