Pre-wedding jitters.Please Help?

I am about to be married soon with my BF whom I know for a brief period of 7 months. I have recently witnessed a sea change in his behaviour,once our marriage is fixed.Now he devotes most of his time talking about our wedding night and sex.He says,he doesn't like to take protection,instead he insist me to take oral pill much before our wedding other wise I may get pregnant on the wedding night itself,He says "choice is yours" He wants me to suck! is that Normal?He has even said he loves public display of affection.What does that mean? One of my friend who got married recently has confessed that she had a bad wedding night.She had thrice on the same night.She could not walk properly on the next day. Does that happen for all? Is there any thing to do with the size!
