How to travel light and keep your orgasm? What do you think.

A few summers from now my friends and I are backpacking through Europe as an early graduation celebration, however backpacking means "pack light, travel fast." Everything I will need for a two month journey will be tightly folded, rolled and stored in one book bag but wait, I can't go two months without my orgasm! If you could bring any sex toys with you, what would they be and why? Consider you will have no power adapter, be sleeping in a youth hostel or hotel and always carrying them with you. Thank you for your input!
