bf felt around in my vagina; feels weird and a little tiny bit of blood right after pee

no you dont have an std from him fingering you vagina. the blood could be for a few reasons tho. 1 he could have broken your hymen and 2 he could have stretch your vagina. hope i helped.

Dont worry nothing is wrong if this was your first time being fingered it is bound to feel strange afterwards as you have experienced something new.
Your boyfriend probably stretched your hymen and at tore and that's where the blood came from dont worry you won't have got an STD from it

If it's your first sexual experience, then it's normal. However, if this condition continues, then you may have a urinary tract infection. Symptoms of UTI are not easy to miss and include a strong urge to urinate that cannot be delayed, which is followed by a sharp pain or burning sensation in the urethra when the urine is released. Most often very little urine is released and the urine that is released may be tinged with blood. The urge to urinate recurs quickly and soreness may occur in the lower abdomen, back, or sides. But do not have to worry about it if you do have a UTI, herbal medicine Diuretic and anti-inflammatory Pill can always get UTI treated completely, you may google it and have a look.
