"I'm going to do a couple of tests here ... let's go together?)" Perhaps the partner himself is tormented by the desire to offer you something similar, and everyone will be happy
I will approach this question from another angle.
If you want your partner or partner to do something, then try to explain what exactly he or she will gain by fulfilling your desire. For example you can say: "I want to have sex with you without using contraception, but for this I want to take tests with you for HIV, HCV and STDs." Thus, you camouflage your demand according to your desire and share the responsibility proposing to do it together. .
My God! What is the problem??? This is a completely normal initiative if the partner is permanent.
When it comes to the fact that you can no longer use condoms, talk about checking as a matter of course.
Let's go without a condom.
Come on. I can go to the doctor the day after tomorrow for tests. When are you?
If the partner starts "I am healthy (a), I have nothing to check", then either run away from such a partner, or continue using condoms (but it is better to run).
In fact, such a question will give a man's pride, but if he is a real man, he will cope and understand the importance of the procedure. The main thing is to let him know that you have good intentions.
In my opinion, this request is completely normal in order to express it directly: "N, I have a request for you: ..."
If you want something especially delicate, you can
1) in the subjunctive mood: "N, how would you react if I asked you ..."
2) through the "I-message": "N, when I think about our closeness, I have both a desire and a lot of anxiety, because the nicest people can be carriers of STDs without knowing anything about it. Therefore, it is important for me to know that the man with whom I am close has been tested for such infections. " ..
Dear, we need to talk.
Yes, honey, I'm listening to you.
I want you and me to visit the doctors for a bit before we creak at the bed.
З.Ы. I don’t think your partner will give up on reinsurance.
