Hi there.
I chose to answer this question because I see you are at your wit's end for a suggestion & empathise with you.
This does not exactly fit into my field of
sexually transmitted disease or dermatology but more an issue for a marriage counsellor. I don't think your husband will go easily to a psychiatrist/
psychologist from what you describe of his habitus. So please do try to identify a doctor cum counsellor near your home for best result & then casually go across for some mundane issue eg hair loss,
tiredness (
anemia) etc & give the doctor prior warning (visit him/her alone before you take your husband along) & then take it from there. If you suddenly bring it up in front of a doctor, it may not sit well with his ego either.
Apologies for playing the devil's advocate but am trying to give you a meaningful suggestion to cope. Is there a child involved in this marriage? Does he have children from his earlier dalliance? All these & more questions need be answered before one can truly suggest remedial or helpful measures.
By behaviour, what else are you implying? I have a feeling this is not just about sex & there are deeper issues running here.
Are you financially viable & working & economically stable or dependent on him? How does the thought of ending the relationship & starting afresh sit with you? Perhaps getting an alternative hobby or a 'release' mechanism for your sexual frustrations et al may help.
If in the Bangalore area, you may call on us at Vikram Hospital or Sita Bhateja Hospital depending on which area you live in & we can help sort your issues out.
Don't lose hope & it is commendable that you are trying to 'improve' your relationship. Do hope we at HCM can be supportive & helpful & you may scour this website to source a suitable doctor nearest you or trace us on the paid private portal of Healthcaremagic.
Wish you happiness & joy all through your life. Good Luck.
