I want my now ex to touch me as well
Why didn't you bring this up when you were together?
I didn't ask for that because I feared that she would question my sexuality
I get that you may regret your past choices, but you have to understand that she is an ex now. You have no right to be involved with her or have her do anything for you. You should have asked for all of this when you had the chance.
I wish she would just never say no.
I'm sorry you are going through a bit of a rough patch, but you shouldn't get involved with your ex. You have to move on and find another relationship and not expect others to do things for you all the time.
