Oh gee, I wish someone as new as you are to the board would have done some more reading of all the threads before posting this, and you would have gotten a good idea of what many of the regular posters here think about this already.
No, I don't think same sex relationships are morally wrong according to my religion. I have been working in my own religious denomination (Presbyterian Church USA) to make its policies more GLBT-supportive for over 30 years, and just recently we finally got a change in the church constitution that allows for the ordination of gay and lesbian persons as clergy. Now I'm working toward official recognition of same sex marriage within our church.
The argument that homsexuality is "wrong on a biological level because we are not physically made to do that" is to me incorrect on several different levels.
First, it confuses biology with morality.
Second, human beings do all sorts of things we aren't "biologically made to do" all the time. Do you think it's wrong for people with poor vision to wear glasses? For humans to fly in airplanes or even to ride in a land vehicle which travels faster than any human can run? For people to cut their hair?
Third, what exactly are you thinking of when you say "do that"? The huge majority of physical activities same sex partners engage in are no different from those that opposite sex partners engage in. In fact, every sexual activity that same sex couples do is also performed by many heterosexual couples.
Finally, this also flies in the face of a great deal of research showing that members of hundreds of other animal species engage in same sex behavior in the wild. Since most other mammalian species don't have long term pair bonding of opposite sex couples, they also don't have long term pair bonds of same sex couples. But long term same sex pairs have been observed in several species of birds where pair bonding is the norm. See Bruce Bagemihl's book for a start on reviewing the research on this (though he is far from the only person to have written on this and there are many different ideas by biologists on just what function same sex behavior serves in various species):
