woman proposing to man???

No nasty comments please.... 
I have been with my partner for 5 years now and we are expecting our 2nd child. 
His I nooooo way the romantic type, even when it comes to birthday & Christmas presents he asks me what I want.. 
Our relationship is really strong... But 
I really want to get married and have been thinking about me actually asking him the big question!! 
Has anybody else done this? If so how did you do it?
