There are many forms of therapy and many methods. Therapy no longer has the same stigma as it used to. Today it's considered normal to see a therapist of some sort. There are many challenging things in life we wish to manage better and things we wish to improve. We no longer live with things as they were. Neither do we accept the same situations that we used to.
However to see a sexologist is not yet comparable to seeing a psycologist. Sex is not considered the most important thing in life, however it takes up a lot of space if it's a problem. In such cases it can be a good idea to see a specialist.
