David and Soccer, Tamar's views are backed up quite well. Sex is a big deal. Deal with it. If you decide to be shomer negiah, mazel tov. You should be proud of your self control, but if someone decides s/he does not want to live a sexually deprived life, you shouldn't judge. Oh, and David, your "sexual compatibility is very easy to develop" bit: not true. Sorry, it's not just. Some people mesh together in the sack, others don't. And those relationships in the "don't" category usually do not last very long.
