You're wise to wait for intercourse if you feel you're not ready. So many young adults rush into it knowing they're not ready, but choose to do it anyway ...
Oral sex isn't for everyone. Partnered sex is a 'whole different ballgame', and it can take a while to get used to and into. If you find there's something your partner could improve to make it better for you, suggest it. Talk about it.
A lot of people find that the first time they have intercourse it isn't what they expected. Not every man ejaculates the first time they have intercourse and many many women don't orgasm their first time either. This is normal, and nothing to be embarassed about. If it's going to happen, it's going to happen ... Not much you can do to prevent, so you may as well accept it.
As for the 'cherry' ... There is no cherry. I believe you're refering to the hymen. The hymen erodes over time, and not every woman will bleed the first time they have manual sex ('fingering') or intercourse.
