Advice on holding a guitar?

I have recently started to play a guitar,the problem I'm having is,I have large F cup breasts which are full and firm,I would like some advice from other girls that can give me some tips on where to put my breast,sorry but I just cant hold the guitar still as I'm playing. Thanks

Since girls haven't responded, I will try to help.

If you watch an accomplished guitar player, they don't look at the fret board while they play. Like most every musical instrument, you have to learn to play it by feel but you have to look at it when learning. I would suggest you try to sit with the guitar face up on your lap and practice moving between different chord positions until you can do it naturally without looking. Once you get there, you should be able to play it in the traditional way.

Also the guitar style will make a difference. A solid body electric will be easier to manage than an acoustic if your style of music will allow that. They also make some "cutaway" models that might be more comfortable and easier to manage for someone with large breasts but your first objective is learn to find the chord positions by feel.
