Update:
I recently combined the fact that the moon was new and in Libra and summoned forth Sargatanas and Sitri in order to try and have some fun again after weeks of studying every day.
I started off by doing the complete yogic breath until my mind was completely free and my body was relaxed and started calling forth Sitri. I welcomed him with upmost respect for coming through so fast and stated him my desires in exchange of a thing he would like me to do for him.
He then told me to summon Sargatanas, which I did immediately after. Sitri did not make a “physical” appearence at the time but his behaviour and voice which was speaking through me remained the same as always.
Sargatanas appeared as a tall, big man in a white robe (he always appeared as a red dragon before). This was also the time when he showed his true voice to me. He shape-shifted from a butterfly.
First things first Sargatanas thanked me for the thread I am keeping up for him and telling me that I’ve brought many great people to him that he is guiding. Both told me that I’ve chosen the greatest time to do aura work and love magick. I stated my desire of having sex with someone which would be brought to me in a healthy way, without hurting anyone including me in the process; and this should be given to me in a time span of their own choice.
The offering they asked me to provide is not for me to question but they told me to go and feed the crows near the train station until they leave.
Not even within 24 hours different girls not only texted me after a long period of time of not talking, but also asked me if I wanted to have some “fun” with them. As I got out from class today I randomly but surely planned by Sitri and Sargatanas, bumped into a girl that had a crush on me a while ago, probably 6 or 7 months ago; which asked me if I’m currently in a relationship after a little bit of small talk.
Afterwards we went for a drink to catch up and she started coming closer and closer to me which made me understand immediately what she wanted. Out of the blue she asked me if she can come over and hang out more because she wasn’t comfortable outside because it was a little bit cold (what a stupid excuse), also my train was about to come so it was either us going our different ways or this. I usually don’t take girls home but that was my only >>free<< day where I had a little bit of time for myself so I said why not. You may probably know what happened after we got to my place so I’ll leave out the rest 
TL;DR: Got laid withing 24 hours after the ritual with Sargatanas and Sitri. What I can say is that they surely work perfectly together and I recommend everyone to try to work with them together at the same time.
I wish good luck to everyone that is practicing love magick
