There is a million threads on this so it would have been better to just done a search to answer your question, but now you'll just know better for next time
.
There is no real clear cut answer to your question though (sounds like Im contradicting what I just said above). Some people say that ejaculating after a routine is bad, and will effect your gains, some people say it doesnt matter. Personally I ejaculate at the end of most of my girth routines and I dont think that it really matters. Although, I do notice a bigger flaccid hang if I don't ejac. but this is just an 'after pump' after my workout and isnt a perminant gain.
So, I say, give your dick a good workout and then have some fun with it, though Im sure other people will chime in with opposing views; thats my two cents.
