Even i am having same experience. I am now 39 (married guy with 7 yrs old son) but 16 yrs back when i was 23 my maternal cousin who was juat 17 came to my place. that time i was upset and in a depression due to my breakup with a girl who belong to different religion. My cousin started supporting me. she was very good and caring. we started enjoying each other's company. we used to spend hours at beach and naturally attracted physically. I kissed her first and she did no object.. after a few days i kissed her lips and she got angry but somehome she was also enjoying. while having lunch or dinner together we used to rub our feets and whenver we got a change we hug and kiss.. but soon she had to leave. she became very sad and cried while leaving. I also felt we are in love but we cudnt do anything as marriage within relation is not acceptable in our religion. years passed. I got married and she also got married. she has one daughter. we hardly met during functions but never had sex. last year during one marriage we met and took a change to go for snax in a restaurant. she hugged me and kissed me passionately and cried. I told her to meet in a hotel because we could not do much at that place. after a month we got that apportunity and the day came. we were so excited. we spent whole afternoon together and had sex twice. we are happy and wish to continue this secret relation.I dont think there is anything wrong as long as we give our love and attention to our partners and kids.
