MadsMum, it's tricky hey. I had a good friend who turned into some sort of banshee when she went on the pill (went off it pretty quickly!).
I was on a low dose pill and it affected me quite a bit too (for me it was libido-wise though), though I didn't realise how much at the time.
So I'm not a fan really. Perhaps you will just have to suck it up and be diligent with the condoms?
