Carlton, could you stop using the wrong terminology? It's becoming offensive.
Normally it's not offensive at all and any one of us would be happy to explain it to you, because it can be confusing if you don't know the particulars.
The tattoo you have IS the correct symbol. BUT, it is NOT a Pentagram. It is a Pentacle. Both are 5 pointed stars, each point having significant and specific characteristics, with the top having the most significance. A Pentagram is an inverted Pentacle, resulting in the Pentagram's two points up. A Pentacle has a single point facing upward. Wicca uses a Pentacle. Black magic, Satanism, Devil and Demon worshipers observe the Pentagram. If you forget which is which, remember that the Pentagram's two upward points are for the Ram horns.
Btw, if you're being advised by a Wiccan that calls it a Pentagram, never take advice from them ever again, they are not Wiccan. Would a Christian forget whether the cross should hang upsides down...didn't think so. It's the exact same for this, no Wiccan is confused as to whether they worship Satan.
