Lagan is Pisces, Rashi is Aries and birth nakstara is Ashwini. Ketu aspects the 7th house of marriage which is never good. Mercury the 7th lord is in the 11th house and combust. Mars in the 8th house makes you mangalik. Your horoscope is weak on the marriage front. Marriage possibility is thereafter 25th year of birth. Delay in marriage can be because of mangal dosha. As your horoscope is weak matching of the horoscope will be important for marital happiness.
