Found this on the internet:
'It is totally safe to do. However, you should put the vagifem in after you finish having oral sex. This way he can avoid having the sour taste of the pill in his mouth, and he wont get any estrogen into his system. Even if he did absorb some estrogen, it would be such a small amount that it won't really matter. But still, put the vagifem in after sex.'
