I’ve been honing my sexting skills recently with a terrific FWB.
Firstly don’t fall into the trap of ‘too much too soon’. If you text something ‘main event’, you’re stuck for a sequel in that sexting thread. So start slow. Don’t give too much detail early. Drop teasing tidbits.
Don’t ignore ‘pre & post’ your meetup topics. I text about my rituals before meetups- things I’m doing to prepare my body, my room, food, etc. And things I do/feel after we’ve parted- physical reminders of him on me, the sexy smell of the sheets, my cat-like satisfaction, etc.
Think laterally- sometimes I send funny musings about sex, that turn into longer (hot) text talks. Yesterday I sent one about how we were so good together we’d need to try bad sex one day, just for variety, and what would that look like? What ensued was both sexy and hilarious (and I discovered I’d missed a trick with him and light fingernail moves 
).
I sext about how I’m wishing him with me while I’m doing very mundane tasks, and how he’d make them more interesting. I got him so het up recently about things we’d do in my laundry that later I sent a pic of just my washing machine and he loved it! Or if he tells me something mundane about his day, I’ll turn it rude instantly. Eg him: ‘l’m building a fence today.’ Me: ‘mmmm yes, you are so good at things that are long and strong’.
Redefine the emojis. Over the months, I’ve found double-entendres for almost all of them, I think! He particularly likes that upside down smiley face one at the moment…. can you guess?
