"Dating" at CCC is not necessarily used in a romantic or sexual meaning, and should not be assumed unless explicitly noted.
For example, "Hacker seeks hacker" is used to connect hackers (e.g. for hacking together), and bogus criteria such as gender, age, or romantic preferences are not relevant.

Feel free to use this site if you're searching / offering anything (e.g. knowledge, things, experiences, persons, jobs). Please refrain from using explicit language in the hub as it can also be used by minors.

Being a beginner, I would prefer someone with more experience than me who is interested in the techniques and how to do things well and want to practice. However, if you have study material, it's also fine if you are a beginner like me. Preferably female body characteristics but this is really about technical side of things so interest in the how-to-do is the most important (male characteristics on my side) I will attend the jam on day 3 but would be happy to practice before somwhere in the congress. Please message here. @jj6
  • Also looking to (pair) dance. Got hooked during last year's West Coast Swing workshop. Open a workshop/session and I will attend it and, if it's WCS, could even help out. -- @vrs / DECT 8770

My only priority would be for both of us to have a fun, safe, comfortable, and satisfying time. If this sounds appealing to you, slide into my (alts) DMs! Ps.
