Hi all,

I was recently informed about a teshuva about shichvat zera levatla, (which I've definitely heard in passing/out of context before) a person had asked a shaila about what to do if he just couldn't stop shichvat zera levatala, couldn't control himself at all -- and the teshuva was that at the very least start by refraining from shichvat zera levatala just on shabbos. It was slightly controversial because at the surface it might seem like an implicit accepting of the aveirah at other times, but the gadlus of this teshuva is that it recognizes that a person can't just stop a bad habit cold turkey and must take small steps towards improving in this (and many) areas.

Does anyone know where I might be able to find this teshuva? I was told it's possibly by the chacham tzvi or chassam sofer - does anyone happen to know? Can anyone cite the teshuva for me if you have it? Would be much appreciated!

It just so happens that I'm learning with someone who isn't so frum and he wants to learn the Chacham Tzvi because he is apparently related to him, so it would be cool if this was a teshuva of the Chacham Tzvi because I would totally learn it with the guy since I think it is very powerful.

Thank you very much!
