So I've been with my bf for 3 years now and we have been best friends for 11 years, and he goes on the weird websites and makes up nasty questions about boobs and want to be with someone who's boobs are as big as possible, now i'm a 36DD should i b enough

am sorry but since when does wanting to be with sum1 dependz on thier bra size ??!!...

very good question.
the taste of a man is very much complicated. he may fall love in your personality and your body shape, but he as well may dislike your breasts type- their sizes, shapes, softness, etc etc.
usually man tends to be keen of other women since they are basically male animal. when they pay some interests to other ladies, they can still keep loving you.
and there are also many, many other facts about men unseen yet to us.
you should not try to find out anything wrong with your brests. instead, you take a silent look at your bf and see what is going on.

I wouldn't worry about it. Doing things like that on the internet is harmless fun. If he meets up with someone else, then you'd have a legitimate worry. But as long as he's just playing on the internet, I'd just try to tolerate it. The more accepting of it you are, the more likely he is to get over it soon anyway.

Do you mean questions like this one....even though this one is not mean?

You boyfriend should love you for who you are not the size of your boobs, the size of them is not important it's the person who makes the relationship, I think that if you started to surf web sites with gorgeous men with big erections and made up nasty questions your boyfriend would have something to say, so perhaps you should pay him at his own game, the next thing you know he'll be wanting you to have breast enlargements
