See in which sign in your chart  Rahu and Ketu are. Now check for the planets following your Rahu or Ketu in  your partner& chart or in Kendra/trines to Rahu and Ketu.

                 Also check planets in your  chart following Rahu and Ketu of your partner.

                  Also check the degrees of Rahu  and Ketu. From these planets we will know about the quality and quantity of karmic  bondage between partners and hence age of relationship that will be required to  complete that karma.

                  So interlinking of theses  planets will show how long the stay between partners will be, to complete the  karma.

                  You can check it in any  relationship between friends ,lovers, partners and children’s etc.

                  Ketu shows the past karma that  is to be resolved and Rahu shows the future Karma. If Rahu combines with the  planet then we get more and we get less if Ketu combines with the planet.

                  Sat of Male follows the  Rahu of Female:- Rahu is an magnifying planet if it conducts Partner’s Sat (i.e.in  case of female Rahu is in Aries and male has Sat in Aries.) it will bring more  and more energy of Sat in your life, Sat is an difficult planet, it is planet  of hard work, obstacles  difficulties,  discipline, criticism, in the long term relationship you will not like these things,  your every work will be judged and criticised.Every thing you do is judged and criticized  sometimes even if person is not like that but you have to resolve those  difficulties and obstacles. Negative.

                Friend or Boss.

                  But if you meet  an friend or boss, whose Sat follows your Rahu. It will be very good friendship  when Sat of friend is on your Rahu. Positive quality of Sat  it is planet of discipline and of self  control,So friend will teach you great many lessons of self-control, discipline,  hard work and you will also learn how to resolve the difficulties.

                Sun of Male in the sighn of Rahu of Female:- Sun is masculine planet,it is  planet of inspiration, it shows your highest quality.It shows most king type of  quality you can represent.

                  When a female meets an male  whose Sun follows her Rahu,then she is fascinated by that person.Rahu  wants  To suck these beautifull  qualties of Sun.

                  She looks on that person like  Hero, that person is always inspirable for her.It is an positive relation,Sun  gives more and more genoristy,it shines more and more light. It gives,gives and gives and does not ask  any thing in return.

                  Female is receiving and Female  is always happy when she receives.Women is un-happy when she has to give in  relationship except love.This relationship can last for long time when the  fascination is strong.

                  Women wants to suck more and  more of the beautifull quality of Man.Whatever quality of Sun, gays has she  makes him to show more and more of these qualities and brings this qulity out  of that gay more and more and sucks these qualties and she is very happy.Rahu  is like hook here she will not allow to get out of it.

            Coclusion:- An positive  relation.

                Rahu of Male in the Sighn of Sun of Female:- Male will still  be fascinated by Solar quality of female, but in love and long term  relationship this is not positive .

              Because slowly and slowly male  will not like the initiative and authoratative and king like behaviour of his  wife.Male do not like this boss type behaviour in relationship.

                  When women is like leader male  feels less and less respected. Initaly it is very strong binding but later on  Male do not like this.Mascculine planet in female chart creates frustration in  relationship. Women is inspiring the gay all the time.

                Coclusion :- Negative relation
