I provide a link for you from the Vatican website about Church teachings on sexuality.
http://www.vatican.va/roman_curia/congregations/cfaith/documents/rc_con_cfaith_doc_19751229_persona-humana_en.htmlYou will note that it is an archaic--even medieval--view of sexuality, that denounces with equal force pre-marital sex, homosexuality, masturbation, and the absence of chastity. There is nothing positive in these teachings, but I think it only right that you read it in order to have an accurate understanding of the teachings of a Church you denounce.
A guest on the PBS Newshour noted that Cardinal Ratzinger had cautioned against discrimination against homosexuals while denouncing their sexuality as a disorder. I myself am not able to understand such a contradiction, but it does seem to differ somewhat
from the Christian Right argument for active discrimination in employment.
