My lip is at 3.2mm, going to 3.2mm hurt but after 2 days its fine. I notice because its nearer an entrance to the body, it would be more tender.

I've been at 3.2mm for about.. 5 months now. I can't seem to get up to 4mm. It's stuck and just wont have it.

Does anyone know what to do? 

Thanks

 Time or tape.

 What do you mean by tape?

Time.. I've gave it enough time?

It could just need more time.

 surely I gave it enough time though, usually... well for ears it would be 1 to 2 months before the next size. This has been longer, and when lets say.. I get to.. 3.6mm on the stretcher/taper it starts to hurt.

1-2 months on lobes is a pretty short time to wait for anything past 8g.

I would just play with a lot to loosen it up and when it's ready you will be able to fit the 4mm in. That is the last place you want to get a blow out... right there on the front of your face. (not like anyone really wants blowouts)

 I'm currently stretching my labret. I have been at an 8g for over 5 months and it still isn't even close to wanting to stretch.  I don't know about your lip but mine is very sensitive I have had two blowouts just from hitting it by mistake.  There are many nerve endings right there you must be patient. Or you could always say fuck it and get it scapeled.

I've not had a blowout. Mines not sensitive at all. I would get it scalpelled.. in 2 years when I'm 18.

I guess I could try the tape method.

The reason it doesn't want to stretch is because its muscle tissue and not just soft tissue, like in your ears. I think If you're only 16, you shouldn't be stretching your lip anyway, and this is coming from someone YOUR AGE.

Yea, I see your point.
I take risks on what I would like to do, I am willing to face the consequences like anyone else who'd take it seriously.

Mm, so it might even take a few more months till its ready to stretch again. Just don't rush it.

The downside of it being at a small size is you don't really know how its going to react to further stretches and you generally wouldn't have discovered any patterns that it may fall into.

Just out of curiosity, what's your goal size?

 my goal size, is only 8mm for now. Later on in life if I believe it's right for me, I'll go bigger. 

 July.. almost August, still not wanting to stretch.It's not sensitive at all though. I can easily slip in a cresent bringing it up to 3.5mm.. but it wont go the full 4mm. I think I'll just do PTFE Tape.

Crescents aren't the best to stretch with.  I don't have my lips stretched (or even pierced), but I would assume a taper would work, correct?  Taper is a much smoother transition than a crescent.  When your body does let you get to 4mm, I'd use a taper, so you can just push the jewelry straight through after...
