It is not impossible to maintain and protect a pure friendship. As long as two people can pay attention to these three taboos, then the relationship between two people can remain pure. Those friends who can play well, but don't cross the line, are always restrained and avoid many sensitive minefields.
First: friends of the opposite sex are opposite sex, not brothers and sisters.
Many friends of the opposite sex even call each other brothers and sisters because they are better, but they are closer than ordinary brothers and sisters. No matter how good the relationship between friends of the opposite sex is, they are never true blood relatives, so they are not brothers and sisters, so it is difficult to have no wild desires for each other.
Don't do too intimate things in the name of brothers and sisters, which is a taboo for friends of the opposite sex. Real brothers and sisters are only kind to each other because of ethics and blood relationship, but friends of the opposite sex are different. It's hard to say whether there are many erotic things in it.
Second: friends of the opposite sex are not boyfriend and girlfriend.
No matter how close friends of the opposite sex are, they should abide by the etiquette between friends. The so-called friendship between gentlemen should be indifferent to water, and don't let it be contaminated with too many desires. Actually, this is easy to understand. Even saints may be tempted to see friends of the opposite sex, let alone us mortals.
Keep a proper distance between friends of the opposite sex and communicate spiritually. Don't have too much physical contact. Excessive intimate physical contact, it is easy to anger friends of the opposite sex, so that the other side of the heart do not have some waves. In order to prevent this from happening, you must keep a proper physical distance from friends of the opposite sex, not too close, even closer than lovers.
Third: don't try to play the role of the other person's lover
If it's only once or twice, and the other person really needs your help, then you can do it once or twice and let your friends rely on it. But please don't treat this behavior as a habit, otherwise it will be difficult to tell who is involved too deeply for a long time, which will make their relationship ambiguous. Friends of the opposite sex can be the closest people to each other, but please put yourself in the right position. Friends are friends. Don't try to play the role of the other lover. What sex people should do.
