The lust issue has been dealt with previously on this thread quite thoroughly. I suggest you read through the thread.
The stumbling block issue is grossly overworked at times. Paul addressed some really serious, deep seated beliefs stemming from very different religious and cultural differences within the Christian community - food offered to idols, kosher food and holy days. At no point did Paul ever advocate setting the standards of Christian life and practice at the level of the weakest believer. That would consign the church to ineffectiveness and loss of testimony. Paul clearly indicates he was not bound by the concerns of the immature. What he did set out was twofold - the strong and probably the most influential must not override people with different views, and secondly, that respect for unity and the other whilst still spiritually immature should characterize Christians when they were together.
As far as any degree of social nudity is concerned Paul's advice should hold - those who would not cope with it should not have that forced onto them, or seen as somewhat inferior, whereas those who can should not be prevented from engaging in appropriate social nudity where that is not an imposition on another - in their own home, a free beach or nudist resort would be fine, but not on a Sunday morning family service for example.
