When I was in the US Navy and stationed in Great Lakes, IL, I went to speak to the on-base chaplin. I was 18, hot and horny ( still am...well not 18 ), and having issues with being into guys and had no idea it was going to be so hard to not act on it with all the nudity and goofing off with sexual overtones and actually being propostioned quite a bit and thinking I was being setup in sting ops to oust gays or bis from the military. I am not a religious person at all, spiritual probably better defines it, but the chaplin seemed to be the only person I could talk to that was basically required to keep my shit to himself lol.
We had our talk and I soon found out that not only was he a devout Christian, but also career military with about 20+ years of service and a 4-star general, as well as a genetics scientist. After about 2 hours of talking back and forth, he complimented me for having such deep and meaningful thoughts for my age and he told me that he wanted to share something with me and joked that if I ever told anyone he said it, he would consider it a break of confidence. Of course, he meant if I told his name in the telling, therefore, I am cleared to share this now.
He said that based on his years of counseling young men and women, gay, straight, bi, etc and with his scientific background and studies and collaboration with other scientists in his field and related ones, it was a common "opinion" that our sexuality is genetically predetermined. In addition (remember that this is a Bible thumpin' Christian chaplin) it is of common opinion that 90% of the population is born bisexual BUT with a predominance to lean either towards heterosexual, homosexual or bisexual. And that, 5% are born to be completely heterosexual and 5% born to be completely homosexual. He also said that it was of common agreement that environment or rearing techniques or life experiences played little part, if any, in the sexuality determination. But, that marriage counselors, school counselors, certain mental health field professionals, religious counselors and advocates, find it an easy explaination to blame those 'factors" since genetic predetermination has yet to be proven with 100% assurance.
I was fascinated by this converstaion, especially with him being so candid in that no matter all he'd been through and his taught beliefs he STILL opted to THINK FOR HIMSELF (something that few people seem to be able to do) and throughout my life I have kept this in the back of my mind. I have met ALOT of people in my life and his (and his colleagues) opinion seems to still hit right on target to this day...at least in my life experiences. ;-)
