I think that if boys and girls like each other, they should establish a physical relationship early on, as long as it's in a healthy context; otherwise, once the novelty wears off, the experience of sex will be greatly diminished.

My friend and her ex-girlfriend were just like that. My friend said that when they first met, the girl didn't want to get intimate so quickly, so they mostly just kissed and hugged.

After talking for three months, she was ready, but her friend couldn't get hard that night, and in the end she had to serve his girlfriend all night with her hands

The next day, his girlfriend asked him if he didn't like her anymore, when clearly he could get hard just from hugging and kissing before.

Friends can only admit that the physiological attraction is fading, but the psychological attraction remains. In short, I am no longer interested in her body, but I am still interested in her as a person.

My friend also once doubted whether he was impotent. I said that it's inevitable for a romantic relationship to have an expiration date. After the novelty wears off, it is the personality, values, shared interests, lifestyle habits, and mutual care that support this relationship. It's normal for physiological stimulation to fade.

Later, with the help of using lingerie and sexual techniques, as well as occasionally taking medication, the friend and her ex-girlfriend's sexual life was somewhat harmonious.
