If his parents are aware of your sexual n financial problems n choose to ignore n still keep demanding, then they are just trying to milk as much as possible. I think you should tackle one issue at a time n try to sort. Figure out if you want to fix the sexual problem first or the financial, try talking sensibly without raising voice, pointing fingers, bad about his parents or judgemental. Regarding the sexual problem, tell him you are not satisfied, some men try to blackmail emotionally or morally making you sound like a sex addict, don't fall for it. It's just their defence mechanism. If you insult a gal in a sexual manner, she will back off is the concept of it. Rise above it. Say if a woman deprives her husband sexually in an arranged marriage, wouldn't he blow it up big n his family too. Why should a woman be silent? N also don't think it's a man's job to start, you can also do. You are half a partner in a marriage. If no talking, convincing, fighting helps, tell him either you will have to tell the whole family or come for a sex therapy. If he points to financial problem for the sexual issue, again don't fall for it. Also find a way n ensure that he doesn't deprive you for giving to his family. Make a scene or whine or something till he gets the message. Sometimes it's important to show them that a wife can't and shouldn't be taken for granted. When in doubt, just ask yourself "how long am I ok to live like this? What am I gona do to change this?"
