4-HO-MET and 4-HO-MiPT are incredible and beautiful psychedelics and generally I would support those picks... but I really doubt the sexual intentions were taken into account very well., Indeed 4-AcO-DiPT (aces) is reported to potentially be pretty tactile / sexy / erotic, and generally some of the 4-AcO tryptamines can be 'energetic' in a certain way, which can manifest as sexual feelings or a body high but apparently also effects like leg shakes or tremors if you are less lucky.
4-HO-MiPT just feels a bit too alien, weird and trippy for focusing on sex if you ask me.
4-HO-DiPT could be sorta okay but is rather mellow and easy, while 4-AcO-MiPT at not too high a dose can also have multiple purposes and be successful.
Sex on 4-HO-MET is probably amazing, don't get me wrong... but make sure you know and trust your partner deeply since it is rather immersive - I just don't think it is ideal for that activity, however superb the drug is.
