You read in astrology that sex is associated with both the 5th and the 8th house. This is confusing to the beginner but I can simplify it for you.
The 5th house rules sex for recreation. The 8th house rules sex for procreation. If you have an emphasis on the 5th or the 8th house in your chart, you probably can strongly relate to this.
For example, I have a packed 8th with nothing in the 5th and I don’t “play” sex. I say that without passing judgement. I know a lot of people who have sex for fun and recreation and see no problems with it. I just know it’s a different function and understanding this can be very empowering.
What is your prevailing attitude towards sex? Can you see this in your chart?
