Yes,you do need to prune it,Kidsgran,but not as much as other varieties of Roses..take out inward growing stems,,to give it a better shape, ..I can see a long one on the right of your pic which might need to go.unless you can see an outward facing bud lower down the stem,,.sometimes they rub against the others,when growing,and they spoil the look of the plant...plus air circulates better if they are open at the centre...the other stems need pruning to an outward facing bud..at a sloping angle,so the rain runs off the pruning cuts,they could rot otherwise.,or die back..you seem to have plenty new growth,so it looks healthy enough..and give it a granular feed for roses..anytime now,and later in the summer..Ideal time to do it now,by the way..good luck,hope this helps ..

Thanks Bloomer I will do what you said, they were very dainty roses and flowered for a long time .

you're welcome..hope you get another good display this year..:o)
