@happycat Are you sure about Drosphirenone being peat approved ? Anyhow i cant find any Drosphirenone here without them being accompanied by estrogen in the pill.
I heard an 8% or above saline solution of NaCl is also a strong spermicide , when dropped intervaginally. Note sure if i wanna test it tho but would be a nice addition to neem oil concoction.
@Ecstatic_Hamster condoms are great but they cant let be do energy/orgone exchaneg experiments that Wilheim Riech was on about lol. Period sex is big no bcoz she cant lubricate or get horny , its not as fun if her kitty isnt also energetically charged.
@JamesL Yeah cervix caps look real interesting , especially with the lactic acid gel (another safe spermicide i think)
