How long to heal up my member, or what's going on?

I've been going at it with my hand too much. Here is my report:

• upper thirties, do have lots of stress

• low dose Effexor (37.5mg)

• cumming 1 to 3 times per day the past six months

• I use my hand, no lube

• starting to take a while to cum, and I really need to beat it to get it out.

• erections don't come easy anymore, and I can lose them halfway through.

• I can only cum in a really supinated position. Legs hanging off the bed.

(It's not porn, I've just been casting a really wide net online and found too much success)
