I have both my traguses pierced. Got 'em done back in the mid 90s. They were both pierced with a straight needle and then a small gold fixed bead ring was worn for the initial healing. I've always worn some sort of ring in them.
Just for thought: nipples and navels and noses are all pierced "straight" and yet folks wear rings in those piercings all the time.
Here's the thing people don't think about when getting a tragus piercing: headphones and ear buds. A pierced tragus can interfere with being able to wear either comfortably. For ear buds, the issue is how much the jewelry crowds the ear canal. I can't stand to wear that style hardly at all. For headphones, the issue will be how large the jewelry is and if the headphones press down on the jewelry or piercing in some way. I've had my traguses get "angry" and a bit irritated from classic-style headphones that fit tightly.
