Post-Breakup Sex Therapy?

So I just got out of a six-year relationship and decided it was time to get back into the dating scene. My therapist suggested trying a sex therapist, figuring that after all this time in a monogamous relationship, maybe there are some things I've forgotten or never learned. But here's the thing, I’m not sure if I really need someone who specializes in 'couple’s issues.' It feels like overkill for solo play and casual hookups, but maybe it’s worth exploring just to see what new experiences await? What do you all think about sex therapists, worth a shot or unnecessary?
