I was on the pill [Ortho Try cyclin [sp?] LO] from age 18-24. It was good for regulating my cycles but it made me a b word as well as destroyed my skin.
The Ring was OK - just weird to put in and it has a chance of falling out and being completely ineffective. Plus, tmi, it made my CM constantly super slimy
Condoms are the best, imo, as they don't effect your hormones but they can fail and they certainly don't help the mood [hey honey, I know you're ready to go but stop a minute and put this on
] plus, I don't know if this is the case for everyone but it dries me right up and if we try to do it for longer than say 20 minutes, I'll be chaffed to high hell by the end
I tried dissolvable female spermicidal strips for awhile, those were pretty great. They are just a spermicide that is in strip form [about the size of quarter a US dollar] and you put one in 30 minutes before sexy time [disclaimer - obviously this wouldn't work in a heat of the moment situation]. They wont mess with hormones or your cm and can't be felt and when used properly have a close to zero fail rate.
All that said - I voted for pull out method as that's the way that we've used for years and it worked well [had zero fail rate] but if you're serious about not having any oopsies then it isn't want I'd recommend.
Good luck with deciding!!
