People who really love you will take protective measures, not for their own enjoyment, but for being responsible for you. To say the least, I will give you a complete solution even if I don't take security measures. Instead of perfunctory you with "it's not so easy to get pregnant", this sentence is just to enjoy the process and avoid responsibility.
To be clear, this man doesn't want to be with you from beginning to end. He must have his own small plan behind proposing Toyoko's marriage. On the negative side, there may be problems behind this blind date. If you think the other person has nothing to be picky about, because you have reached marriageable age, so you get stuck again and again, then I believe there must be something more unexpected. At that time, it will be difficult to get married without getting married. Will involve a lot of things. Maybe you will pay more for the big things in the future because of a small thing.
Never marry anyone because you feel old or for other reasons, and never choose someone who may not love you at all because you are impatient and afraid of missing out. It is wise to treat marriage issues on the basis of equality with a self-esteem, self-respect, self-reliance and independence.
Of course, you may think that he is the kind of person who can't speak, and it may be an unintentional sentence, but what is often blurted out unintentionally is from the heart, so don't lie to yourself or make excuses for the other party. According to the advice I gave you, develop yourself and have a better self to have better things, whether it is love or career.
