She is my girlfriend. I am 27 year old and she is 20 years old. We are in long distance relationship from more than 1.5 yrs. She is quite frank with me but she is not comfortable with me sexually. She often says she do not like to have sexual relationship with anyone. Not even talk abt that. She think she has hormonal imbalance. Her body also not fully grownup. She is quite slim for her age and also she does have very tiny breasts. Pls suggest .is there anything serious or its gonna be okay. I want to marry her but she is afraid they maybe she might not fulfil my sexual need after marriage Pls guide.
