Hi;

If it is only the fumes and not contact that is getting to you, and you do not have a charcoal filtered respirator, consider an M95 mask and a small fan to create circulation.The general guideline is "If you can smell it, it's affecting your lungs. As a last resort you can try card modeling. It's a much more ecologically friendly hobby, can be surprisingly accurate, econonomic, and requires far fewer tools, or airbrushing.
