Should a gay person marry

It's a foolish thing to do because you have raised expectations that you may well be unable to fulfill. You think you'll be able to sexually consummate the marriage, but you won't be able to fake it forever. And if you cannot then she will have grounds for divorce and would be entitled to half your jointly-owned property.

Besides which, a marriage should be based on honesty, trust and mutual concern for each other's welfare - without revealing to your wife the reality of your sexual orientation you cannot tick any of these boxes. You are robbing her of her power by not allowing her the opportunity to decide if she really wants to be married to you.
