My collection of sex toys includes:
1) A medium sized flesh colored butt plug, the first sex toy I ever bought.
2) A double-ended jelly dildo, with a semi-realistic cock at each end. One is long and slim (7 inches long and 3/4 inch in diameter) the other short and fat (about 5" long, an inch diameter. This dildo, which is red in color, has seen a lot of use.
3) An expanding butt plug, like a small pink balloon at the end of a flexible shaft, connected to a bulb that you pump to fill the balloon with air. It has a release valve to let the air out. You have to be careful not to over-expand it--you don't want to hurt yourself inside. I inflate and deflate it several times, just to the point that the pressure is excruciating. I love that.
4) A G-spot vibrator, about 3/4 inch in diameter and 7 inches long. It is made of hard, white plastic, with speed control on the base, and a lovely curve at the tip. I use this when I am in the mood for vibration directly on and around my prostate.
5) A prostate massager, the Tantus Glide. It is purple, with a curved part that rubs against the prostate, and a metal ball on the outside that rubs against the perineum. You insert it and then clench and release your PC muscles (Kegel exercises). That's fun facedown on the bed, maybe rubbing your cock against the sheets or a pillow.
The silicone dildo, #2 above, gets the most use. I like to rinse myself out with a few enemas, then have a shower before lubing myself up and slowly opening up my anus with my toys. Sometimes I watch strap-on porn. Or I make my own video of my anal masturbation session. If I have the house to myself (the wife is out) I get really wild, fantasizing that a woman is fucking me with a strap-on dildo. I verbalize things she would say or that I would say, begging her to fuck me hard and treat me like the slut I am. I yell and moan, especially when I cum. The orgasms are intense, but the process is what is most exciting. Pounding myself with a dildo up the ass gives me great joy.
I've thought about getting a Fleshlight, but I'm more into anal toys.
