What’s the point jumping the sack with someone you’ve newly met and you think you like them? You do not really know the person. Jumping the sack to early just to find out later that the person is no good for you. That’s just hurting yourself unnecessarily and wasting time. Better to use time to find out if the person is worth the bather first. What’s behind the mask of the persons face? Is the personality and interests really compatible? It takes more than a few weeks or a few months to get to know someone. Sometimes acutally several years.
