SPEAK YOUR MIND
As we mentioned at the beginning a jerkoff session is something that may have a bisexual component to it, but up to this point we've only described very roundabout ways of hinting at this. Wanting to masturbate with another man and watch shemale porn doesn't necessarily mean that you would be interested in touching them or tasting their cock.
If you do have anything like that on your mind, speak up! As always, communication is key, it's natural to be nervous about it, just try to be as direct as you can.
