Spa day.
Massage and sauna.

You two could be side by side, naked except for the towel over your asses, getting a massage. And in the sauna, just take off your towel and be naked. If she objects, say she 's being silly, it's only you two, and this is more comfortable.
While making conversation, suggest that you really liked the massage, and were thrilled she seemed to also, while musing that you wished you knew how to give a massage, and if you could, you'd be happy to have her strip down so you could give her a rub down. Say that it would be nice knowing how to give a massage anyways, and it'd make you happy making her feel so good.
