Are you interested in a dildo to strap-on with a harness? Any dildo with a flared base will fit into a harness which is designed to position the base of the dildo over your public bone or mons
Harnesses come in two basic flavors: jock-strap style and thong style. As you???d imagine, the thong-style harness has a strap that goes between your legs, which you may or may not like. Some women find these to be the more stable of the two styles and thus easier for a beginner to use ??? but of course its all individual. (You can also find a harness that straps around your thigh.) You can surf the sites of women-owned sex toy sellers to see the variety of dildos and harnesses. I suggest Toys in Babeland and Good Vibrations for starters. Wielding a strap-on takes practice; you may feel very self-conscious the first time you look in the mirror and see a dildo bobbing between your legs. Try wearing your new strap-on around the house when you???re alone. You can even masturbate while wearing your new strap-on, with dildo in hand, push the base against your mons, thrust with your hips, and notice any sensations in your pelvis. Basically, you are developing a relationship with your nascent energetic cock.
Use plenty of water-based lube and a condom for easy clean-up. Penetrate your partner with fingers before entering her wit the strap-on. All of this goes double if you???re penetrating her anally. But you said she hinted that she likes penetration: she may not even want to be penetrated with a dildo--she may be hinting that she wants to be finger-fucked or fisted. So ask her. (Direct conversation about sexual interests may have been lacking in your previous relationship. Now you get to explore all the forms of sexual expression that interest you.)
