I would really recommend trying ant sex at least once. It’s not everyone’s cup of tea but it’s worth trying at least once I think.
If you are male, just put one inside your dick, it’s the easiest way to start. You can put a little sugary water inside to motivate the ant.
If it comes out on its own, don’t put it back, use another ant if you want to finish. Don’t forget consent is important. No means no.
If it doesn’t come out, your semen will push it out when you cum, but don’t forget to take it out of the goo or the ant will drown.
Don’t masturbate at the same time ! If you press your shaft even just slightly you risk crushing the ant. You wouldn’t wish that to your ant, and it can cause infections.
If urethral stimulation is not enough, you can also put a few ants around the head of your cock. Again, use sugary water to guide them to the most sensitive parts.
As a male, I don’t know as much about female ant sex but I think you’ll have to make them work with your clit mostly. A vagina is too dangerous for an ant and it is at greater risk of dying. It’s also way harder to get out.
What I’d recommend is using a normal dildo/vibrator for vaginal stimulation + ant on your clit, but again I’m not an expert on female ant sex and I have obviously never experienced it
