Some people say that physical friction is the spark of love! Is that so?

I think physical friction is indirectly related to love, but it is not directly related. I think love just wants to be with each other forever. Physical friction may make both sides infatuated with each other's bodies and stay together temporarily, or it may make both sides think that this is the sublimation of love and stay together for a long time, but can you be sure? I think there are more than the former now. Take good care of yourself and don't think that love is simple. I think it is not so much physical friction as exquisite appearance. In short, don't be easily confused by love.
