Dick focused play! Lots of jerking off, mutual, solo and in group. Some guys play with each other and some just like to play with themselves.
To be very clear, the Jerk Meetups do have rules, “No lips below the hips” and “Nothing goes inside anybody’s anything.”
Mutual masturbation between consenting adults is legal AND safe. Probably the safest sexual activity you can do except for solo J/O.
