I personally thing Shulgin was having a very horny time in his life when he was experimenting with 2C-B and the drug is not particularly that aphrodisiac.
That being said of the psychedelics I researched it is one of the ones were the body feelings don't impair penile sexual function.
I'd recommend these for a tactile psychedelic. I wouldn't say the experience is overtly sexual at all, but it doesn't get in the way and like many other activities the experience is enhanced.
