May be you are not in a habit of sharing your bed room or bed with anyone but now you are not single and must try your best to accept this fact. Spend quality time with your wife, explain her about yourself, don't hesitate and don't even avoid her. You have to come forward with your feelings in such a way that you may not hurt her feelings either, this is a life long coalition you have with your wife and this is a delicate relation, you need to put your best effort to strengthen it. Go to bed with positive feelings and get rid of all the negativities and negative people because giving them importance will ruin your marital life before it begins. Plan outings with your wife, built up good memories with her, tell her about your family and friends . She will turn out be a best partner to you if you involve her with yourself and come out of the lonely days and nights, enjoy the new wonderful beginning of your life..........best of luck.

hi dear,
since where you have such problem?
and you did marriage with your will?
how long you both in touch before marriage?
what kind of problem you face to mingle with your wife?
whether your wife is not supportive?
what ever you describe may be suggestive of depressive features so consult local psychiatrist for detail history and treatment.
not to worry much.
Thank you
