I've been in a relationship for a while now, and sex has been great. But lately she seems bored. So she promoted me to ask people about what I can do to spice it up a bit. Different positions, new sexual acts and whatnot.
Pic unrelated.
Ask her what she'd like to try at least once. By doing this with my gf we've tried ffm threesomes, anal, finger in the ass (she loves it), handcuffs, gags, blindfolds, roleplay, shit goes on. Communicate with her and be 100% non judgmental.
