well, for me its something I just got used to seing. I was once a fundie and even when I realized I was an atheist I was still disturbed when I witnessed public displays of affection between same sex couples. In time I made good friendships with both gay guys and girls. I not only got used to they public displays with their partners but also to they way they spoke about their relationships when things got rocky for them. At first it freaked me out but then I realized that relationships are all the same and face very similar issues whether gay or straight. I also learned that love is love and it does not depend on a "right" set of genitals. I found that to be a humbling experience at the time and I have learned a lot from really getting to know gay people. maybe that's what you need; a gay or lesbian friend that will help you better understand these things.
