opinions?

my gf and I have been together over 2 years and we are ttc but everytime we get a donor and its time to do the business they change there mind. we were starting to think about doing it the "natrual" way but we are both really uncomfortable with it but it's becoming a hassle to find and keep a donor we just keep missing my window...should we try natural has any other couple done this if so how was the experience? did you wish you just used a donor ?
