The best options would be to obtain a consultation with a physician who has subspecialty certification in Female Pelvic Medicine and Reconstructive Surgery. A good initial course of action would be start pelvic floor muscle therapy to strengthen some of the pelvic muscles and tissues around the vagina. There are special devices which give feed back while you exercise the vaginal muscles. The best non-invasive approach with zero downtime would be either the Mona Lisa or ThermiVa. If these two options do not work to your satisfaction you may want to consider surgery. But remember there are a lot of unknowns here. You may lose sensation from the surgery or have excessive scaring that may reduce the quality of your and your partners sexual pleasure.
