How do you know you aren't gay Bob? Perhaps social mores and upbringing has clouded your judgment. Are you anti-science as well? An orgasm releases chemicals that create a feeling of pleasure. You claim no moral qualms with homosexual sex and have described it as natural and normal. You hate gays and are intolerant. Increase your odds, unless you are a bigot.
Feelings can't be trusted. Go with the science.,
