Fact from fiction, truth from diction. What feels “right” and what actually is are 2 different things. Back in the dinosaur days you had to put work in, you rarely got to boink a girl less than 8 weeks (and that was rather fast), you usually had to put in about 6 months work.
Say 2 people meet and it “felt right” to hop in the sack the 1st night. You can’t go the next date and just have coffee and a walk because it would seem like a step back given the media and societies believe of its (sex) importance on the relationship. It would seem that once sex is played and not played it because one or both seen less in the other person to the point of not wanting to boink them anymore. And what if in the “feels right” heat of passion no one used protection? Then you have kid on the way but 8 days later because they never got below the foam on top of the relationship they discover they are not a fit. Now there is a problem.
A lot of people confuse the heck out of boinking (lust) and love. They feel if they boinked someone or would, that is a person they love. You should only say you love someone if you can genuinely say that you wish their tomorrows to be better than their yesterdays, and that you’d go hungry that they might be fed, you’d sleep on cold wet ground that they be dry and warm, you would take 100 lashes to the back that they suffer not a scratch. Until you can give yourself over to them and live for their safety and comfort without expecting anything back, then you really love them.
Unless you know 60% about them that on one knows other then their very best friend (if at that) it is too early to go boinking, and you don’t go for swapping spit. What time is the right time? It is hard to say that, but there is definitely a wrong time and one of those is a sheet call the 1st night.
