Maybe try inviting a couple over for dinner that you already know she’d click with. Or suggest a hobby class where you can both go, but give her space to chat with others while you’re there. Even something simple, like a community event or volunteering together, might help her feel more comfortable around new people without it feeling ******. Just keep it low-pressure.
Hi mate you could start with role play in the bedroom maybe introduce a vibe In to the sex so she can feel something in her whilst she is sucking you etc say things like do you like that cock in you and get her reaction
Just an idea
