� what was it/they like to get?
I have had mine done twice. Once before having kids, once after. Both times hurt, don't get me wrong, but it's a good kinda hurt. Endorphins rock

� how irritated did they get afterward?
The first time, mine were more sore than the second. The first time I was pierced, the piercer pierced them too far forward and one migrated, one didn't.
� Does a looser or tighter bra made a difference?
For me, a tighter bra was more comfortable at first.
� Will breast size makes a big difference?
Mine are bigger after kids than they were before, but I didn't notice much of a difference.
� Will it affect the possibility of breast feeding at some point in the future? (I am aware that the jewlery would have to be rremoved at least during feeding times, if not removed completely)
I was able to breastfeed my first child with my jewelry in. I took the jewelry out when he was a few months old. I breastfed my twins after they were born and the only difference I noticed was that there were more streams of milk than when I was nursing with jewelry in.
� What type of jewlery is best to be initially pierced with? (barbell or CBR)
Both times I was pierced, I had CBRs to heal. I currently wear small curved barbells.
