At the recent Birmingham gig the man next to me (who was 5 foot 10ish) had a 5 foot young girl squished against his back. Literally in the groove of his back and looked like she was joined to him! I had a 14-16 year old male literally dry humping me the whole time. If you are comfortable queuing long hours, standing continually (except during the time when they tell you to sit), jumping, loosing your breath as you are pushed against flat metal, pushing back against a crowd and being tenderised like a steak, go for it. Centre barrier is extremely fun but be prepared. There is no personal space, you will end up with multiple people's sweat on you, you will have people try to squeeze in (not to be mistaken for the people grabbing the rail as they feel they need the support) but it'll be one hell of a ride.
