I'm one of those people who really likes using some sort of wipe, before and/or after sex, depending on circumstance. They're especially helpful before sex if, say, you're a sweaty mess but you really want to get down and dirty, or if you're on a camping trip and wanna keep warm with your sweetie, or if you just want to smell and taste a bit fresher when your lover goes down on you. I usually just buy baby wipes, since they're gentle, cheap, and work well. That said, I liked using Swipes, both for myself and for a partner. I'd use them again, but I don't think I'd go out of my way to buy them. Like, I'd love to find them with the free condoms and lube at a sex party.
So first, they did do a good job. My partner wanted to give me oral sex last night, which was the last day of my period, and using a Swipes wipe made me feel comfortable enough to have him do that. And then, this morning, I wanted to give my partner a blowjob before he'd actually gotten up and showered, and he used a Swipes wipe so he wouldn't smell all sweaty. Both times, using a wipe significantly improved the experience for the giver!
However, I was a bit put off by the scent of the "unscented" wipe, enough that I worried about it when I was the receiver. I'm a bit less worried about it after giving oral to a just-Swiped penis, since I actually found that the scent dissipated after a few minutes and at least didn't leave a weird taste. Still, the initial scent is weird enough that I don't think I would replace my pack of sensitive baby wipes, which are more neutrally-"unscented" and, for me, do just as good of a job. When the cucumber ones are back, though, I'll probably try these wipes out again!
