Argument 2, Procreation/Modes Ponens Method

For the sake of this argument we will define homosexuality(H) as sexual intercourse with the same-sex/gender.  That being said, homosexuality is wrong because it does not contribute to reproduction.  I believe this to be true because without adequate reproduction the human race would die. Consider this argument;

Any sexual act that does not lead to reproduction is wrong

(H) is a sexual act that does not lead to reproduction

Hence, (H) is wrong.

Unfortunately, this is not a sound argument due to the fact that there are many heterosexual couples who engage in intercourse while participating in contraception.  Does this make their act of sexual intercourse wrong? The answer is not in today’s society.  There are also cases of some women being infertile. Does this too mean that they cannot enjoy the benefits of being married?
