first time... plan b ?

So I’m having sex for the first time with my boyfriend and I am not on birth control and have no way of obtaining it before we do it. I insist on him using a condom but he says he doesn’t like the way they feel and says I’ll be fine with a plan b because he doesn’t want to pull out. I’d just like to know thoughts on plan b and its accuracy because he claims that it works well (because it isn’t his first time).
