Sun in Gemini, Scorpio rising?

What does this mean? don't use copy and paste info from websites.

I have sun in the seventh house, but mercury and venus in the eighth.

Gemini's are very sociable creatures who love meeting new people to pick their brains gathering lots of information on lots of different topics. Usually quite chatty, not too many inhibitions so are good in large group situations and will more than likely be popular.
You can have a problem with stability in that you fear being tied down in case something more interesting is just around the corner. Quite often can marry late as a result of that and not being to make up your mind (Well you do sometimes, but then you change it again for no reason)
Having Scorpio rising I would say, still makes you a great gatherer of information, who never forgets a fact, but would make you much more guarded with you own personal life. With this info you store up, you can become quite dangerous in the fact that you know everything about everyone and can play little mind games. Or you will play people off against each other, not really to be mean, but just to see what happens and how others will react.
You are probably more highly charged "downstairs" than your every-day Gem, (not that they need a boost) you truly enjoy experiencing different things in all sorts of different places, you're certainly not shy!
Sometimes though, privately you just wish you could find that one special person, just to stop the monotony and enjoy some peace and quiet, but you endlessly struggle with the part of yourself that needs to be on the run.

I'd say that it would indicate a person who's innately very social, versatile and communicative, but it's hidden under a brooding, somewhat withdrawn exterior.

Depending on your degrees, your sun either falls in your 7th or 8th houses.
I reckon since it's closer to the 8th, you have scorpionic tendencies. You are an older soul, here to learn regeneration.
You dwell on the darker aspects of life and find it easier to look from the negative.
The combination of these two energies can make you swing from a chatty, social intellectual to a brooding moodlin. You tend to be a loner because scorpio is basically the emblem for lone wolf.

You need to understand pain and use it as a positive force in your life. From there, things will be regenerated and you can be a positive force in the world.

Also, you need to understand acceptance and apply it to yourself. It is very imperative that you accept who you are because chances are you already know it.

Ps: I know 8th house suns because my guy has it too.
=================

Hi, venus in the 8th will make you exude a certain sexuality that will attract the opposite sex. Alot of screen symbols have this placement.

Mercury in the 8th gears your thoughts towards the intense side.

Sun in the 7th? Is it close to the 8th house cusp?
The sun there gives libran traits. You like company and like partnerships above all else.
