If you and your friend are meeting to have a mutual masturbation, I think you both are ready for it and aiming for it. So anything would do because you both want it. You two can compete who can stay longer time before ejaculation But I wonder why you and your friend plan to have mutual masturbation. You two talked about it or tried it before

Er, what? I watch A LOT of porn and I have never once heard of let alone seen a jock strap be part of anything sexual. Where are you seeing this regularly?
