Two people of the same sex are not permitted to marry each other in Texas. However, the way your question is worded, you leave open the option for a gay man and a gay woman to marry each other, which is legal.
they might be. There are gay people who marry opposite sex partners for a variety of reasons. And while gay people couldn't historically marry, there are plenty of straight people who simply enjoy NOT being married or perhaps haven't been able to find someone for themselves.

They don't want to for the same reason that a straight man does not want to marry a straight man.
