Don't know how old you are but one can go thru several therapist before finding the right fit.
So, don't give up. No need to suffer obsessing about this.
BTW sex therapist, the legit one's, don't touch you & you both keep your clothes on!! It's talk therapy.

Some T's delve back into your childhood or start there to help you.
Some T's help you learn coping skills to deal with current issues.
Just depends on what they feel your need is based on what you tell them.

Sex, under the right circumstances, is a natural, wonderful experience.
Hope you find a T you can relate to & keep posting.
Take care.
