CJ: I don't feel like being nice either, but that is in my nature. Almost, you are going to have to decide SOON what is more important to you...having complete control over this issue or being willing to compromise with a loving and generous heart. If you are not willing to do the latter, then you really have no business getting married to this guy. Sex is a HUGE aspect of marriage. I think it is truly impossible to "quantify" it with percentages, because to you it might be 10% but to your mate it might be 80%. You really have to get out of this mindset that he is WRONG, just as he has to do the same for you. I think that he has a right to expect sex on a more frequent basis than once every 3 weeks, but I also think that you should not be expected to put out, every day 3 times a day. Above all, stop trying to make him feel like a freak for wanting to have sex with you. You are driving a wedge in between the both of you. A person's sexual self is a very integral part of who they ARE. If you are trying to obliterate that part of your partner, then you are skating on thin ice--you will lose a lot more than his interest in you sexually.
I am not even going to comment on the penis size issue, as I do not believe for one instant that were he well hung that you would suddenly want sex 3 times a day. It is an excuse and not a particularly good one either! If you have no sexual attraction to this guy, PLEASE think about entering into a lifelong committment with this person. He deserves to be with a person who feels that way about him.
