Hello and welcome to Healthcare Magic. Thanks for your query.
The transparent and sticky fluid which is discharged from your penis when you are talikng to your girlfriend is likely to be preseminal fluid and not semen. Having a discharge of preseminal fluid without ejaculation when in a sexual mood is normal. So, you don't have to worry about this.
The cramps that you have mentioned is not related to
masturbation. Masturbation is considered as a normal human sexual behaviour and does not result in any bad effects on health. The crams could be due to
dehydration, salt imbalance or due to
fatigue. So, I would suggest that you drink plenty of fluids, take adequate salt in your diet and also include items like tender coconut, banana, etc. which are rich in potassium.
To increase the ejaculation time, you can try practicing certain exercises like Kegel's exercises or techniques like the Masters and Johnson technique. Alternatively, there are medication available which can help delay ejaculation time. So, if this problem is very distressing, I would suggest that you consult a doctor for further help and treatment.
Wish you all the best.
