Hi Jade.
Is there a local BDSM community anywhere near you? Whilst online relationships and research are sometimes the only option due to location, commitments, etc. it would be really useful for you to develop friendships with perverted folk close by. An experienced mentor (either sex or leaning) can be invaluable in wading through the sea of bullshit than newbies encounter.
On a practical note, no, you are bad or rude to hesitate in doing ANYTHING you're not 100% comfortable with. If someone pesters you for a nude photo send 'em one of your naked big toe and block them!!
And keep talking, learning and listening.
