Can you do a split on a dick?

Technically, if someone is flexible enough to do the splits, they could do it on a dick. But it's not something most people can do, and it's not something you'd see outside of porn or extremely flexible people.

The positions you see in porn are chosen because they look dramatic on camera, not because they feel good or are practical. In real life, sex in positions that require extreme flexibility tends to be uncomfortable, hard to maintain, and not particularly enjoyable for either person.

If you're curious about different positions, start with what's comfortable and experiment from there. The best position is whatever works for both of you, not whatever looks most impressive.
