To be a bit more helpful though - you shouldn't like your character. He has a charisma of 3. It should hurt to roleplay that accurately because it isn't something that is likable by it's very nature. So playing a sycophant is not a bad way to go.
I played a charisma 4 character at one point ages ago and the way I did it was by giving him a personal philosophy of radical honesty. He said what came to his mind - immediately, without any filter - even when it was not super socially wise to do so. He KNEW it bothered people, he just didn't care. A high wisdom, low charisma character can very easily end up on the disturbing line as well - he understands people quite well. They make sense to him. He knows why they are offended, when he is being offensive, and what he could do to avoid it, he just doesn't care. Insightful but so lacking in empathy that the concerns of other people just don't enter into his decision making. In addition, the druid I made had no concept of personal space. He would walk up to people, stand half an inch away, and start sniffing their hair and commenting, then going back in for another sniff. I had a very interesting session where my character was just about leg humping the captain of the guard while he asked her in extreme detail about her bathing practices - what soaps she used, where she bathed, did she stuff her bra. Horribly offensive, a terrible individual entirely. But that's charisma 4. He would also rummage through people's stuff, just out of curiosity. Not to steal, but just because he wanted to know. He'd leave his underwear around camp and walk around in the nude.
The character did not last long. If you want to play a charisma 3 abomination who will offend everybody who he meets, most GMs will eventually have it hit you in the head - and that's fair.
