Diebetes and sex problem. Consultation.

Hi, Just four month back, i come to know i have sugar (385, 10.9%), i gone through proper treatment and following diet and all, currently its reached to 151(6.9%). While having sex i have got extreme feelings and while in intercorse, its climax in a minutes. But same if I do masturbating it goes 10-15 min and some time with no climax. To increase time I tried viagra 50 &100 but no use. If i use condoms climax gets delay by more 4-5 mins. My wife needs 40 mins foreplay before having intercourse. But i can't go till time. Please suggest preferbly ayurvedic treatment. Secondly she didn't feel any sensation after discharge by me or herself. Her vaginas also very tight at starting while inserting penis which may affect my early ejaculation. We need baby, as our both age is 37, and we married before one year back, So need proper consultation.
