Seriously, don't drink ur own semen. Although semen is associated with the idea of masculinity, simply drinking semen is unscientific at best and insanitary at worst. To get stronger, start a plan consisting of nutrition and weight/bodyweight training as well as a general fitness program that trains other aspects of fitness along with muscle strength. Try this:
Nutrition:
1. Eat a lot of hearty food like whole grains, veggies, and meats
2. Since u seem like u have a fast metabolism, eat 5 meals a day instead of 3

Fitness plan:
1. Do some cardio exercise twice a week: try jogging or jump roping
2. Do some stretching twice a week (note: I mean stretching for the sake of stretching for long time periods, not just stretching before/after working out). Stretch out ur whole body
3. This is the bulk of ur workout since u want to get bigger, try:
-two sets of 15 pushups per day no matter how tired you are
-two sets of 5 pullups (not chinups) per day no matter how tired you are
-two sets of 15 squats per day no matter ur fatigue, once normal squats get easier, try doing squats while holding dumbells
-two sets of 15 calf raises per day, once normal calf raises get easy, start doing them with dumbells in hand
-two sets of 45 bicycle crunches per day (you want nice looking abs right?), once these get easy, do bicycle crunches with shoes on
-for 3 days of the week (maybe alternate this with the stretching/cardio days) do 2 sets of 5 reps of the following exercises:
-bicep curl
-tricep curl
-wrist curl (don't neglect those forearms!)
-lat pull down
-bench press
-lateral raises or military press or shoulder shrugs
-leg presses

Hope this helped

I think somebody just told you to drink your own semen just for a mean April Fools laugh. Don't do that.

What MMA suggested, while I haven't read it, is too specific to take seriously (no offense bro). It differs for every person, while later on the set/weight/repetition for size gain will be generally the same, but initially it can vary significantly. For instance, if you are a completely unexperienced weight trainer who lives a sedentary lifestyle, as opposed to an active lifestyle of playing basketball every day, or a person who used to work out, your work out schedule will be significantly different initially.

Give us a more specific detail of your life if you want us to formulate an effective work out plan for you. Literally, tell me your life story, including medical related history (surgeries, deformalities, diseases, family genetics (if you have any conditions or might have any conditions your parents can pass on, and the body size and shape of your parents/siblings), the type of lifestyle you lead on a typical day, if you have ever exercise and what did you do if so, etc.

All this, is necessary to formulate a good work out schedule.

However, none of this means anything, if your mind isn't 100% willing and determined to achieve this. We can only go so far for you, most people who have at one point stated a physical goal for themself (getting bigger, slimmer, stronger, etc), have never succeeded. Statistically as well, if a personal trainer who gives you a work out schedule, cannot attend your work outs, the client typically does not do it. It is a shame people cannot motivate themselves. Do not become one of them.
