Yes, wanting to use the 'pullout' method is a bad idea. A really stinky idea which is likely to leave you pregnant.
If you're not willing to get contraception and have sex with a your boyfriend who's waited soooo long for you, done everything for you and who adores you, I suggest you set him free to find someone who's willing to meet his needs.
Though I will warn you that if you're not willing to compromise on this thing about living together first, you're going to be a virgin for a loooong time. If you're fine with this, then that's great. But do be aware of the consequences of your decision.
Never regret anything that has happened in your life. It cannot be changed, forgotten or undone. So, take it as a lesson learned and move on.
