Hi again Raven
I'll be brief, for now, because it's bedtime, but yes, it is normal, I think, to find someone else attractive, even if one is in a committed relationship.
Problems only start when someone acts upon the 'crush'.
As for the pill, I understand that its long-term use may not be healthy. Check it out and ask your doctor or nurse for information and advice.
Perhaps you should get some stronger condoms
