Goatboy-
No, not talking about manually stimulating her. You said you had limited use of your hands, so I didn't want to start reeling off suggestions for things that you're physically unable to do. e.g., if I was in a wheelchair, one of the very first things I'd focus on making my signature move would be waving girls over and having them come sit on my lap, chatting a bit, then pushing them off of it and telling me they're giving me a hard-on, while continuing to banter with them, to set up all of 1.) physical dominance, 2.) compliance, 3.) sexual vibes, and 4.) address any lingering question they might've had in their minds about my sexual function or faith in my own sexual ability. But, I don't know if you can wave your arms to gesture women over, or use them to push them off, so I don't know how feasible this is for you.
I don't know anyone in a wheelchair personally (let alone a guy who games), but what I've heard from friends with wheelchair-bound buddies who game, and what I've heard from some of my more creative friends who've been bedridden for a while with feeding tubes in them, etc., and managed to sleep with hospital nurses, has mainly been using commands to order women around and get them putting the work in.
When it comes to sex, I would focus on getting very good at heightening women's arousal very high before you actually begin penetrative sex. That'd mean lots of foreplay, with LOTS of teasing, and starting and stopping things, bringing her close to climax, not letting her go over, etc. With penetration, I'd study tantra, which you can probably find a way to do (even if she has to be the one on top doing it) - simple tantra is 9 deep thrusts, 1 shallow thrust; then 8 deep thrusts, 2 shallow thrusts; then 7 deep thrusts, 3 shallow thrusts, etc. This is not very labor intensive, but is quite exciting for the woman, because she WANTS to have deeper thrusts when the shallow thrusts occur, but you are not giving them to her (or not letting her have them, if she is on top).
I've had women cum minutes into (sloppy) penetrative sex after prolonged build up; most of the anticipation prior to sex is emotional, not physical. If you are teasing her and turning her on and making her want it but continually taking it away right when she feels like she is about to get it and instead giving her something different, getting her into that, getting her excited about it, then taking THAT away, and so on and so forth, you can bring her to the point where she is basically ready and waiting to climax on receiving you.
I'd also advise you to experiment and see what you can come up with for sex. Be creative. You might even find a way to retrofit your bed to make you a good lover - e.g., if you wanted to do adapted missionary, and you have enough use of your arms that you can grab onto a girl's shoulders and yank yourself forward, all you'd need to do pull it off is something creating downward force on you pulling you back - getting a spring-based system that attaches around your ankles and pulls you back down, then using your arms around her shoulders to pull you up, probably does the trick nicely.
If you really want to do it, there's almost always a way you can do it if you're willing to be inventive enough in figuring out how.
