Why do i or should i have to beg for sex form my wife this is bull ****?

i should not have to beg for sex for my wife.I thing this is bull shits.then i guilt her in to it and she gets made. sex 1 every 2-3 month is bull **** i have gave up asking and take of my self because she wants to me a nun.before you married you get it all the time and after you married you don't get it at all.She mad at me for trieing.That pisses me off. So i do my own thing and she still gets mad. so i took up working more and fishing in my spare time to avoid the aggravation. and that make her ever made because i am gone more i can barely touch her half the time. I am starting to give up any physicall contact at all because she thing any time i touch her i just want sex.So i got a boat and got deeper in to fishing and any time we go to a lake for a picnic she get pissed i want to go fishing.If i wanted my virginity to grow back i would have of not got married. the best yet when she does say yes she give me 5 minutes. i need more then 5 minutes trust me.
