Cap or diaphragm  

Apart from the issue I'm currently dealing with (it getting stuck inside of me), I LOVE the diaphragm. I found out I wasn't never fitted (which is why it kept getting stuck upon removal), so my new, awesome doctor actually sized me. It's easier than popping in a tampon once you learn how to do it and then ya pop it out the morning after sex. No side effects, no hormones, no emotional hangover. It's very hard to find though. Pharmaceutical companies don't want women to buy one silicone object that lasts for the rest of your life, so finding the right size and actually getting it has been a challenge. My mom used it and only got pregnant to have me (her only child) and I've been using it for 5+ years with no issues.

Cap or diaphragm  

I've used Caya several times over the past couple years (they last up to 2 years- due for a new one now). I use it on the edges of my fertile window (with fertility awareness) and/or combined with withdrawal or condoms to boost efficacy during the fertile window. Always use with Caya/Contragel- they come with an applicator to re-insert the gel into the vagina, as you need to reapply the gel each time you have sex. Watching the YouTube instructions on how to put it in (plus the instruction manual in the box!) helped me understand how to use it properly and to have an idea of how it was inserted properly.

Cap or diaphragm  

I used the caya cap. It has been a game changer after previously taking the pill. I feel in control, no need to remember to take a pill, just put it in when needed. Better than condoms as it is women based and not detectable. Effect of not taking hormonal contraceptives has been amazing. All the side effects that I had ( migraines, reduced sex drive, dryness, breast tenderness, strong period pains, breakthrough bleeding and emotionalness) all gone. I wish someone had told me about it before!

Female condom  

Same as the male condom, has no side effects and will protect from STIs and pregnancy! The only thing its a little fiddly to get on and if you don't react well to latex then not ideal!

Female condom  

These condoms prevent me from getting UTIs, I can't have sex without them! I think it's because the part of the condom that sticks out covers my urethra and prevents bacteria from spreading. They're a little hard to use at first, and some brands are better than others, but I highly recommend them to everyone.

Female condom  

Tried it a couple times with different partners. Mixed reactions. I practiced inserting prior to anything, so it was easy, especially after a couple of tries. Sex felt no different for me and one of the partners. One didn't like the appearance and the other the feel. One thing I love is that it doesn't have that nasty latex smell! You can also use any lube. Overall, I think it is a great option for many people, but (like everything) you should try it a few times for yourself. Also great if you run into situations where the guy is resisting wearing a condom himself.

Used it once - it came off inside me within 5 minutes and I didn't realise so ended up having completely unprotected sex and having to get a STI test.
