How do multivitamins influence sexual side effects of propecia?

I have been taking a multivitamin for a little while now. I recently missed a day of taking it and noticed the following day that I was able to ejaculate much better and it felt like I actually released more/most of what was in there and felt much more satisfied and complete afterward. Is it possible for any of the nutrients in a multivitamin to exacerbate or influence the sexual side effects of finasteride?

yes , some products often contained in multivitamins can cause similar effects as fin
saw palmetto , nettle , soy isoflavons etc
you need to post the ingredients of the tablets up here to be fully sure
