We've all heard men complain that condoms are tight, that the feeling isn't that good. The feeling is probably really different with a condom than without, but...
... if you don't know the person, if they you don't trust that you are the only person in his sex life, tell him, ok, then go ahead there will be no sex.
If he insists on having sex without a condom, then consider is he the right person for the relationship, or even a casual relationship or a one night stand.
Why? Because he thinks only of his own satisfaction and transfers all responsibility regarding the pregnancy to you, and is irresponsible regarding sexually transmitted diseases. If he asks you to have sex without a condom, it was probably no different with all other sexual partners.
Of course, you can take birth control pills, wear a diaphragm, use another form of birth control - it's all your choice.
If you don't want to use a condom, it's your choice, but you should be aware of all the possible consequences – from possible pregnancy to possible health problems due to birth control pills and sexually transmitted diseases.
If you want to adapt to his needs and give him more satisfaction, so be it your choice and no one can force you to do so. It's not right for him to ask you to have unprotected sex and assure you that it's so impossible to get pregnant that he knows how to watch.
You have to be responsible to yourself. And don't have sex with a person who insists on intercourse without a condom.
Before every unprotected intercourse, both of you must see a doctor, he a urologist, and you a gynecologist. And, do everything possible tests for sexually transmitted diseases. This step should not be skipped, as the consequences can be extremely large.
The point is that contraception must be a matter of agreement and both partners must be responsible for it. Insisting on sex without a condom without testing and choosing another form of birth control - shows how he is an irresponsible and even uneducated partner - and so are you, if you let him.
