Love is good, but not every act of “love” is moral since there is a difference between charitable love, and the moral quality of an act. Homosexual acts are intrinsically, disordered, and gravely contrary to the moral law. Homosexuality, a.k.a. sodomy is talked about at least 6 times in the Bible including in Leviticus 18:22 & Romans 1:26-27, hope this clears up some of the confusion you may have.
