It looks like the word you are looking for is 童貞 どうてい for virgin
Seems like the second line could maybe be interpreted two ways, as どうのこうの or どうの千 using 'K' as 'thousand' but as どうのこうの is most used for things being said, not actions by my understanding, I am assuming this means 'many thousand' in this case.
TenkograbEh?Please give that back to me.Just leave it to me and before you know itI'll be doing this and that with one or two or maybe thousands of virgins
