early ejaculation and soft erection

I've read other replies on here and other sites..
but non of them seem positive to me..

I've been masturbating quite often lately or forever..lol..,

(It may be a stress reliever, not having sex lately or too much masturbation..)
(...Ive been kinda overly stressed lately, moved from home town and starting up new business, so haven't had sex in a while.)

..but have stopped for the past few days.
because I've started to notice that I'm not getting a full erection like I used to and am cumming too soon..

At first I though my penis was shrinking..lol..but then realized the problem.

Can someone please give me an answer to why this might be happening, and is there a way to resolve it???

If i were to answer myself id say due to, too much masturbation and porn!!!
Or overly stressed.

But seriously is there an explanation and way to fix or resolve this.
Please say there is.

I don't want to be stuck with this when having sex.


Thanks and hope to hear some good news..
