Thanks Jonty. I haven't regularly bottomed. Always found it painful, but a couple of times recently its been enjoyable. This was just something else so keen to add to it.
Totally get that mate. Fill your boots and trust your instincts.
I think the key for punting in this area is that you have to be even more careful as to your choices and decisions. Probably teaching you to suck eggs but for any other interested parties I'd suggest this means...
The right SP (does she do everything you would like her to do? Do you fancy her? Do you think you'll "click")
The right equipment (nothing worse than visiting an SP and it looks like her peg is something from a joke shop)
The right time (you want to be able to have adequate time before, during and after)
