Dont worry about it,do you trust the coach.If its a good gym where common sence prevails there should not be a problem,theylle put you in to move the good fighter round. he should just touch you,and move to give you confidence.Its easier than sparring a novice.Ill always remember telling this F/weight one day he was sparring with Roberto Duran,He shit himself but asked later if he could spar again, He loved it said he,d learned so much.Duran had nothing to prove,thats how it should be.If you get beatup change gyms its no good
