Hi, I've got a couple of newbie questions, I've had a scan through this forum and found loads of good info, but if any one could clear up these for me, I'd appreciate it!

1:mouth guards, should they be soft or hard? Mine is rock hard and rubs on my gums a bit, making my mouth sore after sparring (even when I've taken no head shots) can I get one thats a bit more "gummy"?

2:Boots, I'm training in regular sneakers at the moment, I'm not against buying some proper boots but will they make that much difference in the gym for casual training sessions and light sparring or should i save my money and spend it on t'wife?

3:Why does getting punched really hard in the head feel good? I mean it hurts like hell, but I kinda get a buzz off it and always come out of the ring smiling after I get a beating!
