Aye Carumba!
Yes, absolutely. Therefore, send your seniorita north to me and I will prevent her from ruining your PE program. I know it’s a big thing of me to do for you, Mexican, but HEY!, that’s the kind of guy I am.
Or, you could really just make her a part of your PE program and get her to do all your squeezing for you.
OK, seriously… What you are talking about is two things. First, does ejaculation affect gains? For that I suggest you research the subject ‘masturbation’. Even though it’s with someone else, we are still talking about ejaculation.
Second, you are talking about the physical stress of having a hard-on during sex. Well, we have them at night and can’t prevent them. I don’t know if having sex before or after PE will hurt you. I will say that I think you might find your penis feeling very, very fatigued. So in essence you might be wandering over into overtraining land. All just things to consider.
But hey, who am I to say what is what? Just alleviate yourself of the nuisance of that pretty girl and send her to me. I promise I’ll do everything within my power to see that she has no need of squeezing your penis AT ALL!
And you don’t even need to thank me or pay me. I am pretty unselfish about these things. :)
