charging sigils

ok... strangely intimate question. but i've (19) been doing some research and watching some videos and. i've been drawing some sigils but i always hit a roadblock when it comes to charging/activating them. pretty much every single place i've read it has said to activate a sigil by masturbating. tmi but i am on some meds that make this impossible. i know chaos magic is kind of a 'to each their own' thing, so does anyone have ideas on how to work around this?
(and if anyone wants to add in other tips for beginners, that would be welcome!)

edit: i wont take the time to respond to each and every comment, but i have read all of them and have put thought into them. thinking of getting a metronome and meditating on that. ive got a list of books to read now, as well! thank you so much, everyone <3
