Welcome Helios, if you are new to magic my humble advice to you is to combine NAP with the Franz Bardon's "Initiation into Hermetics" training.
I always having good results with NAP but i discovered when i align myself mentally, psychically and physically to magic; the results are very well increased.
I do not know who you are invoked, probably the love & relations entity but all NAP invocations with variety of intentions let it be success, money etc. does effect on "Sexual Attraction" for me.
Look to my first thread on this forum "Nap effects in just two days", i first evoked Nitika for monetary matters and i had a day like a rockstar as all girls trying to seduce me! Maybe it is also a hidden intent of mine and Nitika well knew it.
