I think it should be done or not. This is something agreed by both parties. Under normal circumstances, it will not be said that either party has to ask for sex. You have to understand a few questions. 1. First of all, there is no denying the problem of ideas. Most people don't want their other half to have sex with their ex. But whether you mind, whether you will regard this as a burden for two people together and have a bad feeling is another matter. If two people are suitable, have been together for a long time, have feelings, and everything goes with the flow, then there is no need to entangle. 2. Then consider whether this person is actually the person you want to entrust for life. Don't have sex when your mind is hot. Now the society is open, but who hasn't booked a virgin yet? After all, the openness of society is limited now. I said I could accept my other half for the first time. 3. From the perspective of love itself, love is a beautiful thing, which may be hard to expect in life, and many things don't need you.
