yeah, i had a 2" round glue bottle i use to fuck myself all the time and a sort of fuck machine i made.
see my latest pics for details

Still use the ole "prison pussy" once in a while...

I HAVE A LONG SECTION OF SPECIAL PCV PIPE (LARGE DIAMETER AND TAPERED AT ON END). IT FITS PERFECTLY ON A VARIABLE SUCTION VACUMNE AND CAN MADE ME HARD AND CUM IN A FEW MINUTES!!
I HAVE TO INSERT MY LONG COCK WHEN HE IS COMPLETELY SOFT OR HE WON`T FIT!!

I used to have a piece of foam pipe insulation that was the perfect fit! Wore that sucker out!

I take condoms and fill with water then freeze them....wow what a rush to fuck your ass with one of these.

I've made lots of sex toys for myself. One of my favorites is the prostate massager wand. I took 6- 1 inch diameter wooden macrame beads(they have a quarter inch hole drilled through them) and glued them a quarter inch apart on one end of a 10 inch long wooden dowel. I coated the whole thing with three layers of melamine paint to seal and make it slippery smooth. Works and feels great stroking my prostate with it. Gets the precum flowing pretty quick. I've been able to achieve a few fantastic orgasms using it alone.

bicycle pump, lube it up, and up it goes!

I have made a boatload of various dildos from a variety of different materials and have made self fucking machines from a variable speed sawzall to a windshield wiper assembly from an old car .

oh i love doing that can make them pretty big and so good as they slowly melt and get smaller

not sure if it counts as home-made, but i've always loved playing with my ass with whatever i could find around. pens, pencils, markers, toothbrush handles, screwdriver handles, random (non-sex) toys, etc. i've always had a sweet-spot for pens and pencils, as they were the first thing i played my ass with, and i love trying to keep fitting one more, stretching my pussy open.

two more things that i really enjoyed and i can suggest to you: stick a condom in your ass and start to fill it up with marbles, see how many you can hold before you push it out without using your hands. and the sane with ice-cubes. put them in directly, you don't need a condom, but have a tower ready because they will melt inside of you, i wish i could find someone else to do these things together.

I have used a mouse sander with a soft cloth over it… feels so good on my cock I can cum within minutes and it’s so strong and long lasting

I made a powerful BJ machine to use while driving or even parked. Some plumbing parts and a proper diameter radiator hose was connected to the engine vacuum.
There was a control hole on the piping-a finger cover it for the strongest suction-the opposite when released. It could be pretty intense especially when I bounced my finger up and down on the hole. Make one for your self but careful while driving. The vacuum hose was plugged when not in use.
