I can understand your concern. Firstly psoriasis
is just a skin condition and it is not a hinderance to get married. Secondly as far as libido is concerned it seems more of psychological or stress
induced. Psoriasis as such is not directly linked to libido.Try to remain stress free, do mind calming exercises as stress can also exacerbate psoriasis. There are multiple treatment options for psoriasis depending on its extent, severity, response to treatment and recurrence. Don't be disheartened, consult a good dermatologist
and discuss your problems at length. Psoriasis is a recurring skin problem which can be kept in remission with proper treatment. Keep in touch with dermatologist even if the disease is in control. Usually recurrence occurs with stress, fever
, use of wrong medicines and sometimes discontinuation of medicines. Take care.
