For me it is the opposite - I love wearing a hood and it actually puts me in a submissive mood... however, I can understand the claustrophobia. Try a domino mask first, then work up to full face and include occasional blindfolds etc. Make sure you also work on trust - use a safeword (even if you don't normally) which means 'take the hood off now'. That way you know it can be removed at any point and this helps build trust and safety.
