Question: By what age I’ll get married ? As I’ve already surpassed the normal age of getting married.

Rahul,
According to Vedic astrology my observations are as follows:
1. Gemini ascendant and lord Mercury is in the house of profession, and giving strength to its house of family, mother, happiness and related matters. Ascendant lord is in paapkartari yog, but ascendant has no affliction.
2. Spouse house lord and Profession house lord is same – Jupiter but retrograde, placed in the house of neighbor, indications are that you may marry with some person either related to office or neighborhood or both. Since Saturn and Jupiter are conjunct with Mahadasha lord Mars and Rahu, indicating that you are not showing any courage, you must try, so that your position will be clear. There is a possibility of more than one relationship or liking, possibility of bedroom pleasure or marriage may start after December 2013.
3. You have to give your efforts for the marriage, otherwise marriage may be delayed till Feb. 2016 on wards.
Since you have opted for free service, I have not tested navmansha chart (which is important for marriage purpose).
