OK So first!! Everyone calm down. Take a deep breath. So you want sex and she seems ready so you think its best with her- bluntly speaking?! Right!! She too is kind of ready it seems. So dude, I am not so sure about the bad karma angle… maybe its more in your head than actually happening?! One thing is seemingly more certain and that is that your guilt is killing you , for a while now. Dude, frankly speaking, guilt is not a good place to be. It keeps nagging at you and makes you half the man you are. So either you get over the guilt or the relationship. Make a quick decision and then irrespective of what happens, stick to it!! Don’t let your cuz talk you into anything thereafter , be really firm and unavailable. Read this column and see if it helps and take a few steps back to decide what you want to do. My “advise”, decide coolly, but quickly. All the best, bro https://lovematters.in/hi/news/should-i-have-sex-my-cousin
