First, professional massage therapy only massages on areas like muscles, joints and not on private areas. Gluteal work or butt massage may also be included depending on the type of massage BUT even if gluteal techniques are used, you will still be draped properly. If this makes you feel uncomfotable you can ask your therapist not to include this. Massage therapists concentrate on areas that needs kneading to relieve pain and soar muscles and not on sensual areas so there will be a slim chance of feeling sensually aroused. But if you get an erection, professional massage therapists and technicians are trained to handle this properly. They will not feel awkward but will instead make you feel that its normal. Nothing persomal because sometimes its a physiological effect to relaxation BUT even if this is a valid reason- at any time- you can ask your therapist not to include certain areas you feel will not be comfortable with you.
Massage in itself is a pleasurable experience but not intended to sexually gratify a person.
