go for it!
I once had the pleasure of spending an eventful evening with a young lady who, announced part way through the festivities, that she had already had her bachelorette's party and was getting married the next weekend...kept talking about her hubby-to-be, then got back to business.

If it's all in good fun, no strings attached, between consenting adults, just be sure you "vulcanize your tool".
