I was like you only i had slept with 45 men without ever experiencing an intercourse cllmax. Then i settled down with someone got clean had a child and did lots of pelvic floor exercises and hey presto i experienced my first sexual intercourse only cllmax at 35!!. Lots of things helped - making love not just casual sex- being honest and open with my partner, definately the pelvic floor was great, sorting out my emotional trama's from the past, not using drink and drugs and generally beginning to feel good about myself.
