You should be able to feel your cervix by inserting a finger into the vagina- to me, with my partners, it feels kind of like a hard rubber stopper (firm, less rubbery/not siliconey like many dildoes) about one inch long held in place at the rooftop (most inside part, closest to the head, not the front, closest to the belly) of the vagina. The uterus is connected to the vagina through a passageway in the cervix. (Cervix is Latin for neck, and it kind of feels a bit like, and is about the same diameter as, a chicken neck, for you non-vegetarians)<div>
<br></div><div>As your uterine lining sheds while you approach menses, you will experience the cervix descending closer to the entrance of the vagina, and can roughly measure the distance inside to determine where you are at. Count knuckles, generally speaking- if you&#39;re not at least an index knuckles worth in, you might not be in the right place. As with everything, this shouldn&#39;t be painful.</div>
<div><br></div><div>When you are most fertile the cervix fluid is thin, and is (potentially) different from other fluids in the vagina, and it is thicker, more like mucus, other times. You can keep a log of cervix distance and texture of fluids when you touch your cervix with the tip of your finger.</div>
<div><br></div><div>If you monitor the above and restrict intercourse to the later portion of your cycle, it should be a highly effective means of contraception. You can also measure the cycle by inserting an ordinary thermometer into the vagina and observing the cycle of temperature, which for some people is less &quot;icky&quot; than the finger method.</div>
<div><br></div><div>Men who have sex with women can benefit from learning and logging as well. If you generally perform cunnilingus as foreplay, using a finger to learn her depth over time is an excellent way that you can play along, too. I use a lunar calendar to track, which is not perfect, but is perhaps a little more discreet.</div>
<div><br></div><div>Everyone can benefit from seeing a cervix live: Annie Sprinkle used to use a speculum and a flashlight to show off hers. </div><div><br></div><div>If you are interested in what app my partner uses, please let me know and I will ask.</div>

help you do it.<br>
<br>
HOWEVER, this app is asking me questions I don&#39;t know the answers to -<br>
how do you tell where your cervix is? is cervical fluid different than<br>
the regular goo that comes out of my vagina? how do I tell my<br>
temperature?<br>
<br>
Did the non- annoying period app ever get made? now that I understand<br>
what it&#39;s for, I am interested in helping on this project. I&#39;m using<br>
ovuline mostly. I like the interface, although I am annoyed that ALL<br>
PERIOD APPS (except two) assume (1) I am a woman, (2) I am trying to<br>
GET pregnant instead of trying to AVOID getting pregnant.<br>
<br>
Check out &quot;MyGirls,&quot; it is a very amazing cultural artifact made by<br>
two Russian physics graduate students in washington state. It assumes<br>
users are men.<br>
