I have been married for 5 years and everything was perfect for first year and then my wife started ignoring sex. We were very open from the beginning but still she started making excused to refuse having sex. sometimes, she cuddles in the middle of night but she always tell me to lick her pu$$y, sucking her b00bs and fingering but she refuse upfront to have sex after that and does like doing oral sex to me.

Now i am losing interest in my wife.. What should i do ??

Please guide.
