Yes, there are historical and fictional accounts of rituals or practices that involve the use of virgin blood in certain cultures or belief systems.
This is a false dichotomy. There are Sunnis who are Sufis and there are Sufis who are Sunnis. There are Sunnis who are not Sufis and there are Sufis who are not Sunnis. Being a Sunni means to follow the Prophet Muhammad (SAW) and his blessed sunnah. Being a Sufi means to be even more strict in following this sunnah in an effort to rectify yourself spiritually. Many people claiming to be Sufis are in fact, NOT Sufis if they deviate from the sunnah. Many popular scholars from the past and present have been Sufis. Ibn Taymiyyah, Imam Ghazali, etc. have all been Sufis and Sunnis.

The Greater Jihad is a central part of Sufism, and consists of numerous rituals and dances to promote a connection to God and improve their relationship. The most important of these rituals is the Dhikr (ذكر) where a Sufi will spend 60-90 minutes reciting the names of God repeatedly to achieve a trance-like state and connection to God. Probably more famous, though, are the dances that some orders of Sufis perform to "court" God, of these, the dances of the Mevlevi Order, also called the Whirling Dervishes, have become part of UNESCO's Intangible Cultural Heritage.
