Something Iv never done before

So lately Iv been trying new things with my partner. Iv only ever done anal once and had a bad experience so I vowed I’d never do it again. However, since I’m starting to get my confidence back and I’m trusting my partner to look after me when we are having sex that I let him ‘slip a finger’ and OMG the orgasm was unbelievable. I mean wow I really enjoyed it and never thought I would. Would it hurt so bad if I let him give me full anal? What can we use if I do let him?
