No condom?

So I got the implant December 8th. My boyfriend and I have always used condoms even after I got the implant. I kinda want to try it without a condom so how do I bring that up to him? Like I mentioned it to him the other day but he was like no thanks I don't want kids but I'm on the implant. I know there is a really slim chance of getting pregnant on any birth control. I think I'm mainly freaked out about the precum. I really want to try it without a condom but then again I kinda don't want to risk it?
