Maybe, but we are long distance and he doesn't have health insurance so I can't see him doing that while he's visiting.
The thing is I know he isn't with any other girls. I am not suspicious of that. I'm more worried that he's going to think I think he's done something wrong, because I think it's a logical concern.
For me, it's more I want to establish this habit from the beginning so that every time we have oral sex we use a condom. That way if something *does* change down the line he doesn't think I'm suspicious of him. People lie. I don't think he's lying now but I think he's capable of lying later, just like every one else on this planet is. And that's not really a risk I want to take. If something happens later, he will have the conflict of either lying to me and possibly giving me an STD or asking to use a condom and me suspecting he has cheated or something. If he's going to lie to me I'd rather not get an STD on top of that.
