Is it possible to contract any sort of std from a handjob (with lubricant)?

STDs: Remember there are twelve common stds. It is every sexually active persons responsibility to know what these are and how to prevent them. The situation you describe is of course very low risk for stds. The only situation that may be possible is transmission of the wart virus as a skin to skin contact. But, at 37 you are much more likely to have been exposed to hpv long ago.
