When doing a condom demonstration I like to use an ejaculating condom demonstrator with UV sensitive fluid (artificial semen) and a blacklight to show that semen can still be present on the penis (and hands) even if they look clean post “ejaculation”. This highlights the need to be careful post coitally and not to get intimate again without clean hands/another condom etc, otherwise you maybe at risk of sexually transmitted diseases or unplanned pregnancy.
I recently ran out of my Health Edco UV sensitive Fluid and although it is £6.95 they have a minimum order charge of £20 plus its about £10 P&P so in order to try and save money I thought I would have a bash (no pun intended) at making my own. I do also have this non UV sensitive artificial semen but its very grittty (eh?! and Urgh!) and tends to go off after a year plus the lack of UV sensitivity ruins part of my demo, so I tend not to use it if I can.
A discussion on twitter on how to get UV sensitivity suggested laundry brightener and then just a white liquid soap or shampoo for the “semen”.
UPDATE 10th March 2014. Have found a much better way. Scroll to end!
So you will need the following:
A clean jar (I just washed out my old jar of UV sensitive fluid). Some laundry brightener (about £3) and some white liquid soap (about 90p).
I filled the jar three quarters full of soap and stirred in half a sachet of laundry brightener.
Something very odd happened. The previously powdered laundry brightener clumped into hard solid lumps…..
and so far I have not been totally able to get rid of them. However the UV sensitivity is excellent!
I ended up adding the rest of the sachet of brightener and topped up the jar to full with the liquid soap.
The solution has oddly gone runnier than it was when the two things weren’t mixed- I thought it would go a bit thicker with a powder being added to a thick liquid, so I am pondering adding some cornflour to thicken it up! It also doesn’t have the slightly translucent quality that my previous jar of UV sensitive fluid (and real semen) does and to be honest it looks a smidge radioactive in the jar (tinge of fluorescent yellow/green)! Overall, I am reasonably pleased with the result even if its appearance isn’t as good as the Health Edco stuff, the UV sensitivity in my homemade stuff is far superior making this demo much more obvious when working with larger groups and since it is so much cheaper to make then I’m happy!
By the way real semen would probably glow under a black light but not to the vivid extent that my homemade artificial stuff does! My homemade artificial stuff also smells very strongly of soap and laundry unlike the real deal which many say smells like Bleach but heck its in the same genre of “cleaning fluid smells”. ;) Ha!
I have enough liquid soap and sachets of brightener left to make up about 3 or 4 more batches (so £1 a batch instead of £20!) but as I only use 3-5ml at a time (the average ejaculation size) per demonstration, then I think this lot will last me a while so long as it doesn’t react/go off in the coming weeks. I will keep an eye and keep you posted.
Hope this post helps any cheapskate sex educators out there :D. If you would like a copy of my 25 page indepth guide to doing a condom demonstration with young people (or anyone over 13 really) then you can email me on firstname.lastname@example.org it costs £3.50 or is provided free on condom demonstration training courses I deliver, just contact me for more details.
Turns out white hand soap on its own is UV sensitive (feel a bit silly for not trying that first and faffing with the laundry brightener! So basically you can ignore the entire post above but leaving it for posterity of the daft things I do for my job). I bought an 80p one from the supermarket and I will easily have enough for thousands of demonstrations. The added bonus is it will not clog your demonstrator, usually when training I pack away hurriedly and sometimes forget to flush the tubes of the demonstrator. One time I was doing a training and the tiny plug of artificial semen that rose majestically from the end of the demonstrator caused a hysteria that was hard to come back from
so to speak. But I have discovered that hand soap doesn’t seem to solidify in the same way as have just flushed the tubes with water as I am training this arvo and it was all clear and soapy fresh. :D
