How do I convince a new boyfriend to get an STD test?

I just started going out with this guy, and I told him he needed to get tested for STDs before we go any further in our relationship.

I already made an appointment with my doctor to get a full panel of tests, so that I can show him that I am safe.

He doesn’t want to do it. He insists that his last girlfriend got tested even after they broke up, and her results were negative, so he’s gotta be OK.

There aren’t any “red flags” that make me think he’s infected with something; there are no weird bumps where there shouldn’t be, and there’s nothing leaking inappropriately (lol).

I’m not out of line for asking for him to get an STD test, am I? Is it rude? Would you be insulted?

I would respect someone if they wanted me to get tested, because it would show that they were being responsible, and that’s attractive to me!

I don’t know if I should break up with him, or just let it go and trust him.
