Every time I look up anything about lesbian sex I only get answers, research, and other sources that focus on cis lesbians. I’m trans and my partner is trans. There’s a lot about trans lesbian sex that isn’t talked about very often. Every so often you have folks who recommend “fucking trans women” which is increadible but doesn’t cover everything.
Now if you’re like me and my partner you’re on estrogen and anti depressants which means that your genitals don’t act like they’re “supposed” to and it makes being able to cum really tricky. With regards to genitals (assuming you haven’t had bottom surgery) it is likely the case that your “ penis” functions more like a gigantic clit. If you play video games it’s a lot like downloading a clit emulator on your dick hardware. Some may say that due to the lack of nerve endings compared to a clit, it’s not the same as the “real deal” but after comparing notes with my cis lesbian friends, it comes close. Really really meaningfully close. Especially if you’ve had an orchiectomy because then it means when you come you barely ejaculate and the head only slowly spews out a bit of a saline line solution. Basically you can get wet.
Aaaaaall of this is to say, if the pre-bottom-surgery genitals of trans woman function with striking similarly to parts of a vulva, especially the clit, then it is to say that thribbing is possible for trans women. And if that IS the case then scissoring is very extremely doable.
I had this hypothesis recently and I texted it with my partner. To great success!! We tried frotting several times with disappointing results. On a whim I go “ hmm hey wanna try scissoring?” My girlfriend gave me this look of “how would that work?” We both shrugged and gave it a try. My recommendation is use lube and if you are uncircumcised pull back the skin on your head. If you are able to get hard it might be a bit trickier but either way, hard or flacid, you can grind on each other for a lot of satisfaction. In my experience the head has to be involved for maximum sensation. I know the tendency is to go “well it’s just gonna flop around everywhere” but trust me, rubbing our parts together was easier than we both anticipated. And it felt better than we expected too. My gf came and went “this works???? Why is no one talking about this?????”
I haven’t tried this with a cis girl so I have no data to know how this would go in that case. But can confirm that it worked in my case (two trans women without bottom surgery)
Much like muffing, not everything is for every girl and that’s ok. If you try this and it doesn’t work for you no biggie. But I just wanted to write this to say that it’s not just the cis girls and the trans girls with vulvas and vaginas out here scissoring. If you’re trans and you haven’t had bottom surgery you can do it too!
So the next time someone begs you to penetrate them politely yet firmly slap them and instead, with their consent (or the consent of a better person) pour lube and rub your genitals on theirs. We may have dicks but we do not owe ANYONE penetration, or any other sex acts that don’t affirm our gender.
