I want to have sex with my fiance
Did you and your fiance agree to wait until marriage?
We did but I'm a sexual person. I really miss having sex.
Wanting to have sex with the person you love and are going to marry is normal and makes sense but you two are a special case. Because of your agreement you need to contain yourself until you get married. I wish you the best of luck in the future and I hope you don't try to force them to do anything.
I just know I will be okay and I'm not forcing her. I trust her and she's a great person.
That's good for the both of you. Good luck.
