Most cases of premature ejaculation do not have a clear cause. With sexual experience and age, men often learn to delay orgasm. Premature ejaculation may occur with a new partner, only in certain sexual situations, or if it has been a long time since the last ejaculation. Psychological factors such as anxiety, guilt, or depression can cause premature ejaculation. In some cases, premature ejaculation may be related to a medical cause such as hormonal problems, injury, or a side effect of certain medicines.

Thing 002: Portal Cake

January 28th, 2012

The 19th was my birthday! As befitting my station I commanded my MakerBot to make me the cake from Portal.

It imported into ReplicatorG at 1cm across, which it printed in under a minute. You can see just a hint of cherries, but the resolution was too small for more than a tiny stump of candle. It left the doily off entirely.

I doubled the scale to 2cm, which including a raft took about 10 minutes.

I redoubled it to 4cm across, which took about 40 minutes and almost failed: a draft caused the left side to curl up, threatening to detach the raft from the build platform, leading to certain doom. Heedless of my own safety and mocking Death itself I leapt into the maw of the MakerBot and secured the cake to the build platform with a piece of tape. It finished, complete with candle, and my birthday was saved.

By my very rough estimate it’s about a 50-layer cake. Take that, southern grandmas I read about in the Times.
