Yes you may never have menses, or children, but certainly you can marry and have a normal sex life. You need to check your vaginal length, by a gynaecologist, and if it is small, a proper vagina can be created by surgery. If it is normal, no problem. You can select a groom, who already has children, or marry someone who is not interested to have children, and if you tell your medical condition from the start, when you marry, there will be no conflicts and pressures later on.
