No sex

Alexandra • I am a 20 year old over weight woman. All I want in life is to have a child and I do not understand why I cannot get pregnant.
Why is it I am engaged to the most amazing man ever but he won't give in to sex... I can make him hard as a rock and he will deny me.. It has been 10 days since we have had sex and he could wait months before he wants it again.. I don't know. It sucks though...
